2010-07-06external-toolchain: hardcode the destination directory for a libraryThomas Petazzoni
Until now, the function copy_toolchain_lib_root was copying a given library to the target filesystem by assuming that it should be at the same place it was in the toolchain sysroot. However, with Buildroot hiding libstdc++ in /usr/<target-name>/lib(64), this isn't correct, and it is probably safer not to rely on the toolchain organization anyway. Therefore : * Instead of having a single EXTERNAL_LIBS variable, we now have LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS, which respectively list the libraries that should be copied to /lib and /usr/lib. As of today, only libstdc++ is part of the second list. * The copy_toolchain_lib_root takes another argument, which is the destination directory of the library, relative to $(TARGET_DIR) Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-07-06external-toolchain: handle libstdc++/libgcc_s for BR toolchainsThomas Petazzoni
Most toolchains have their libraries either in /lib or /usr/lib relative to their ARCH_SYSROOT_DIR. Buildroot toolchains, however, have basic libraries in /lib, and libstdc++/libgcc_s in /usr/<target-name>/lib(64).

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.

2010-05-24Improve gettext integrationThomas Petazzoni
Having a BR2_NEEDS_GETTEXT option, as introduced by 54d64798e1e14b526c3cc1142961972cff9f1e8a isn't sufficient to express the different kind of dependencies on gettext. This commit, based on an idea by Peter Korsgaard, introduces two different options : * BR2_NEEDS_GETTEXT, which is true as soon as the toolchain doesn't provide gettext itself (i.e, when the toolchain is uClibc based, be it an internal or external toolchain) * BR2_NEEDS_GETTEXT_IF_LOCALE, which is true when the toolchain doesn't provide gettext *and* locale support has been enabled in Buildroot.

2010-05-20Add a BR2_NEEDS_GETTEXT optionThomas Petazzoni
When using an external toolchain that uses the glibc or eglibc C libraries, compiling a separate gettext and libintl is not needed and is even a source of confusion, causing build failures. These build failures are due to the fact that when libintl is compiled, it replaces the C library libintl.h by its own, which does #define gettext libintl_gettext. Then, when packages want to use gettext, autoconf realize that gettext is available in the C library and therefore do not add -lintl to the LDFLAGS, causing the build failure because the program has been compiled to use libintl_gettext but this function is not available. Therefore, we should only use gettext if a uClibc internal toolchain or a uClibc external toolchain. If an external glibc toolchain is used, gettext shouldn't be used. In order to implement that, we introduce the BR2_NEEDS_GETTEXT option, which is hidden to the user, and whose value is computed automatically from the rest of the configuration.

2010-05-07libxcb: fix path to Python modulesThomas Petazzoni
When building libxcb, the variable XCBPROTO_XCBPYTHONDIR must point to the location where the Python modules needed to run the c_client.py program are installed. The path $(STAGING_DIR)/usr/lib/python2.6/site-packages was hardcoded. However, it doesn't work when the version of Python installed on the host is Python 2.5. Therefore, add a little bit of magic to compute the host Python version. We also verify that Python is available on the host, as we don't build it in Buildroot. Fixes bug #1531.

2010-04-17external-toolchain: Support for multilib toolchainsThomas Petazzoni
Multilib toolchains provide different versions of the base libraries for different architecture variants. For example, the ARM Codesourcery toolchain provides base libraries for ARMv5 (default), ARMv4t and Thumb2. Depending on the -march= argument passed to gcc, the sysroot used by the compiler is therefore different. This means that the sysroot location in CROSS-gcc -v cannot be used. Instead, we must use CROSS-gcc -print-sysroot when available and fall back to the old way if unavailable. Moreover, we cannot simply copy the full sysroot as we used to do, because the sysroot organization of multilib toolchain is more complicated. In Codesourcery toolchains, we have : / etc -- for ARMv5 lib -- for ARMv5 sbin -- for ARMv5 usr -- for ARMv5 (includes headers) armv4t etc -- for ARMv4t lib -- for ARMv4t sbin -- for ARMv4t usr -- for ARMv4t (no headers!) thumb2 etc -- for Thumb2 lib -- for Thumb2 sbin -- for Thumb2 usr -- for Thumb2 (no headers!) So we have the default ARMv5 architecture variant that is installed in the main directory, and we have subdirectories for the ARMv4t and Thumb2 architecture variants. Copying the full sysroot to the staging directory doesn't work. All our packages are based on the fact that they should install libraries in staging/usr/lib. But if ARMv4t is used, the compiler would only look in staging/armv4t/usr/lib for libraries (even when overriding the sysroot with the --sysroot option, the multilib compiler suffixes the sysroot directory with the architecture variant if it matches a recognized one). Therefore, we have to copy only the sysroot that we are interested in. This is rendered a little bit complicated by the fact that the armv4t and thumb2 sysroot do not contain the headers since they are shared with the armv5 sysroot. So, this patch : * Modifies how we compute SYSROOT_DIR in order to use -print-sysroot if it exists. SYSROOT_DIR contains the location of the main sysroot directory, i.e the sysroot for the default architecture variant. * Defines ARCH_SUBDIR as the subdirectory in the main sysroot for the currently selected architecture variant (in our case, it can be ".", "armv4t" or "thumb2"). ARCH_SYSROOT_DIR is defined as the full path to the sysroot of the currently selected architecture variant. * Modifies copy_toolchain_lib_root (which copies a library to the target/ directory) so that libraries are taken from ARCH_SYSROOT_DIR instead of SYSROOT_DIR. This ensures that libraries for the correct architecture variant are properly copied to the target. * Modifies copy_toolchain_sysroot (which copies the sysroot to the staging/ directory), so that it copies the contents of ARCH_SYSROOT_DIR, and if needed, adds the headers from the main sysroot directory and a symbolic link (armv4t -> . or thumb2 -> .) to make the compiler believe that its sysroot is really in armv4t/ or thumb2/.

2010-04-17external-toolchain: support libraries outside of /libThomas Petazzoni
The copy_toolchain_lib_root function was making the assumption that all libraries were stored inside the /lib directory of the sysroot directory. However, this isn't true for certain toolchains, particularly for the libstdc++ library. The function is therefore reworked to find the library and its related symlink either in /lib or /usr/lib in the sysroot, and copies it at the same location in the target directory.
