2010-07-29Fix computation of REAL_GNU_TARGET_NAMEThomas Petazzoni
The current computation of REAL_GNU_TARGET_NAME is incorrect for non-ARM glibc platforms because it generates something such as mipsel-unknown-linux- as the REAL_GNU_TARGET_NAME. So we correct this by : * Adding "gnu" in the suffix when glibc is used, so that in the previous case we will have mipsel-unknown-linux-gnu * Improving the ARM_EABI code to correctly append "eabi" when glibc is selected, so that we have arm-unknown-linux-gnueabi, and to append "gnueabi" when uclibc is selected, so that we have arm-unknown-linux-uclibcgnueabi. The little trick here is that LIBC and ABI aren't completely orthogonal on ARM. This fixes problems such as : checking host system type...

2010-07-26Makefile: fix ldconfig selection for internal toolchainsPeter Korsgaard
Commit ed0d45fdd (Choose host/target ldconfig based on availability) added a runtime check for a cross-ldconfig being available. Unfortunately this checks runs too early (at package/Makefile.in parsing time), so it always fails when using an internal toolchain as ldconfig isn't built yet. Fix it by moving the check to the only place it is used (target-finalize). Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-07-18Choose host/target ldconfig based on availabilityMalte Starostik
Decide whether to use the host or target ldconfig based on an availability check instead of internal/external toolchain selection. An external toolchain may very well provide an ldconfig while the host's one may fail.

2010-07-07Merge TARGET_CONFIGURE_ENV into TARGET_CONFIGURE_OPTSThomas Petazzoni
TARGET_CONFIGURE_ENV defines CFLAGS, LDFLAGS, CXXFLAGS and FCFLAGS, separatly from all other variables that are part of TARGET_CONFIGURE_OPTS. This is useless and not consistent with the HOST_CONFIGURE_ variables, therefore we merge TARGET_CONFIGURE_ENV into TARGET_CONFIGURE_OPTS and fix the few users of TARGET_CONFIGURE_ENV.

2010-07-07Remove $(TOOLCHAIN_DIR)/bin and $(STAGING_DIR)/{usr/bin,bin} from the PATHThomas Petazzoni
These shouldn't be needed. Even when the cross-compiler is in $(STAGING_DIR)/usr/bin, we anyway use an absolute path for TARGET_CC, TARGET_LD and al. Not having $(STAGING_DIR)/{usr/bin,bin} in the PATH will avoid having Buildroot trying to run target binaries. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2010-07-07Cleanup TARGET_CONFIGURE_OPTSThomas Petazzoni
The definition of CC, LD, GCC, CPP, CXX and FC shouldn't contain the CFLAGS/LDFLAGS/CXXFLAGS, those should be passed through the appropriate variables. However, the --sysroot option is a particular case here: it needs to be part of the CC/LD/GCC/etc. definitions otherwise libtool strips it from the CFLAGS/LDFLAGS.

2010-07-07Rework sysroot option handlingThomas Petazzoni
The external toolchain and internal toolchain cases both need to use the --sysroot option, and they have almost identical LDFLAGS/CFLAGS/CXXFLAGS definition, so we can factorize these definitions. Moreover, the --isysroot option is implied by --sysroot so there's no need to specify both. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2010-07-07Solve the host tools relying on host libraries problemThomas Petazzoni
We build host tools installed in $(HOST_DIR)/usr/bin, and some of them rely on host libraries in $(HOST_DIR)/usr/lib. So when these host tools are executed, they need to find the host libraries, which are not installed in a default location. In c1b6242fdcf2cff7ebf09fec4cc1be58963e8427 we tried to use LD_LIBRARY_PATH when building target packages to solve this problem. Unfortunately, LD_LIBRARY_PATH is not only used to find libraries at run-time, but also at compile time. So it leads the build of some packages, such as icu, to fail. Therefore, in 0d1830b07db4ebfd14e77a258de6fb391e57e960, we reverted the LD_LIBRARY_PATH idea. The other option to solve this problem was to hardcode a RPATH value in the host binaries that would reference the location of host libraries. We added this -Wl,-rpath option to HOST_CFLAGS in 6b939d40f6a29a43277566adc9d4312d49cb3abf. Unfortunately, this caused problems when building binutils, as reported in bug 1789 so this change was reverted in e1a7d916e9eeaa215551740de40c055130d6c073. Then, we tried to use -Wl,-rpath in HOST_LDFLAGS, but it was causing problems with fakeroot not recognizing 'ld' as the GNU linker, since the -Wl,-rpath cannot be understood by 'ld' directly, only by 'gcc'. This commit is a new attempt at using HOST_LDFLAGS, but in this case we modified the definition of HOST_LD to *not* contain HOST_LDFLAGS. LDFLAGS are being set separatly. It solved the fakeroot issue and was tested against nearly 300 packages of Buildroot.

2010-07-06ext-toolchain: Fix ARCH_SYSROOT detectionThomas Petazzoni
For the detection of the ARCH_SYSROOT_DIR (which contains the C library variant specific to the compiler flags), we used to pass only the -march argument instead of the full TARGET_CFLAGS. This was done because TARGET_CFLAGS contains --sysroot, and we don't want to tell here the compiler which sysroot to use, because we're specifically asking the compiler where the *normal* arch sysroot directory is. Unfortunately, there are some multilib variants that aren't decided only based on -march, but also on -msoft-float or other compiler flags. Therefore, we take the opposite approach: pass the full TARGET_CFLAGS, from which we have stripped the --sysroot option. For example, this allows a PowerPC CodeSourcery toolchain, on which we're using the soft-float multilib variant, to work properly as an external toolchain.

2010-05-06Add staging libraries directories to -L in external caseThomas Petazzoni

2010-05-06Add -rpath option for host package compilationThomas Petazzoni
In c1b6242fdcf2cff7ebf09fec4cc1be58963e8427, we added $(HOST_DIR)/usr/lib to LD_LIBRARY_PATH when building target packages, because the build of target packages sometimes require host tools installed in $(HOST_DIR)/usr/bin which themselves require host libaries installed in $(HOST_DIR)/usr/lib. Unfortunately, this solution didn't work, as libtool then tried to link target binaries against host libraries. So $(HOST_DIR)/usr/lib got removed from LD_LIBRARY_PATH in 0d1830b07db4ebfd14e77a258de6fb391e57e960. However, this meant that we went back to the previous situation, in which host tools used during compilation of target components might require host libraries. An example : make[2]: Entering directory `/home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/build/xfont_font-adobe-100dpi-1.0.1' /home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/host/usr/bin/mkfontdir /home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/target/usr/share/fonts/X11/100dpi /home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/host/usr/bin/mkfontscale: error while loading shared libraries: libfontenc.so.1: cannot open shared object file: No such file or directory Therefore, we try another solution: make sure that host binaries are linked with an -rpath option, so that $(HOST_DIR)/usr/lib doesn't need to be in LD_LIBRARY_PATH for them to find their libraries.

2010-05-03package: Add $(HOST_DIR)/usr/lib to LD_LIBRARY_PATH for host but not targetLionel Landwerlin
Some packages like icu requires to be compiled against the host system first to be able to compile against the target. This is due to the usage of self generated binaries by the package to build itself. When the generated tools also depends on generated libraries it is required to add the path to these libraries in the library path (LD_LIBRARY_PATH) especially for the configure step. Adding $(HOST_DIR)/usr/lib to LD_LIBRARY_PATH for target compilation might break the link step by mixing host libraries and target binaries.

2010-03-31toolchain: prepare for more than two alternativesYann E. MORIN
Lay down the path to add more than two toolchain kinds: - check the type of toolchain as: ifeq (toolchain_buildroot,y) blabla buildroot-specific else ifeq (toolchain_external,y) blabla external-specific endif - prefer using positive checks, a-la: ifeq (foo,y) instead of: ifneq (bar,y) (where foo and bar are mutually exclusive) - have the toolchain_buildroot case always appear first - gettext is handled differently, because we want to add an option only if not using the buildroot toolchain, hence we use ifneq.

2009-08-08Remove --without-html-dir from DISABLE_DOCUMENTATIONThomas Petazzoni
In an attempt to disable the compilation and installation of documentation of gtk packages, a DISABLE_DOCUMENTATION variable containing --without-html-dir has been added to package/Makefile.in. This variable is used by package/Makefile.autotools.in so that --without-html-dir is in effect passed to all autotools-based packaging relying on the Makefile.autotools.in infrastructure. Unfortunately, --without-html-dir doesn't work. It leads libglib2 ./configure script to think that HTML_DIR is "no", which leads to the installation of the documentation in $(STAGING_DIR)no (yes, with the "no" suffix at the end). The issue is that --with-html-dir is not an enable/disable type of option, it's an option that only allows to pass a PATH for documentation installation. As we don't want the documentation to be installed in this odd $(STAGING_DIR)no directory, we simply get rid of this option. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
