From 8dcc6736aba672916bd4bc70a964c30bb11eeafa Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 25 Jul 2005 22:59:58 +0000 Subject: Added -linker option to mklib, used to specify a particular program for linking, if relevant. Updated Makefiles to use -linker option instead of setting CC, CXX env vars. --- bin/mklib | 100 ++++++++++++++++++++++++-------------------------------------- 1 file changed, 39 insertions(+), 61 deletions(-) (limited to 'bin') diff --git a/bin/mklib b/bin/mklib index e8c58c5668..06436ff388 100755 --- a/bin/mklib +++ b/bin/mklib @@ -15,12 +15,14 @@ # -patch N specifies patch version number (default is 0) # -lLIBRARY specifies a dependency on LIBRARY # -LDIR search in DIR for library dependencies +# -linker L explicity specify the linker program to use (ex: gcc, g++) +# Not observed on all systems at this time. # -cplusplus link with C++ runtime # -static make a static library (default is dynamic/shared) -# -install DIR move resulting library file(s) to DIR +# -install DIR pu resulting library file(s) in DIR # -arch ARCH override using `uname` to determine architecture # -archopt OPT specify an extra achitecture-specific option OPT -# -noprefix don't prefix library name with "lib" or any suffix +# -noprefix don't prefix library name with "lib" nor add any suffix # -exports FILE only export the symbols listed in FILE # # The library name should just be "GL" or "GLU", etc. The 'lib' prefix @@ -29,10 +31,6 @@ # # objects should be: foo.o bar.o etc.o # -# Environment variables recognized: -# CC C compiler command -# CXX C++ compiler command -# # @@ -43,6 +41,7 @@ MAJOR=1 MINOR=0 PATCH="" DEPS="" +LINK="" CPLUSPLUS=0 STATIC=0 INSTALLDIR="." @@ -62,6 +61,7 @@ do '-major') shift 1; MAJOR=$1;; '-minor') shift 1; MINOR=$1;; '-patch') shift 1; PATCH=$1;; + '-linker') shift 1; LINK=$1;; -l*) DEPS="$DEPS $1";; -L*) DEPS="$DEPS $1";; '-cplusplus') CPLUSPLUS=1;; @@ -120,12 +120,13 @@ case $ARCH in 'Linux' | 'OpenBSD') # we assume gcc - # Set default compilers if env vars not set - if [ "x$CXX" = "x" ] ; then - CXX=g++ - fi - if [ "x$CC" = "x" ] ; then - CC=gcc + if [ "x$LINK" = "x" ] ; then + # -linker was not specified so set default link command now + if [ $CPLUSPLUS = 1 ] ; then + LINK=g++ + else + LINK=gcc + fi fi if [ $NOPREFIX = 1 ] ; then @@ -133,13 +134,7 @@ case $ARCH in echo "mklib: Making" $ARCH "shared library: " ${LIBNAME} #OPTS="-shared -Wl,-soname,${LIBNAME}" # soname???
