Dear all, I have some issue regarding Libtool and my external toolchain (located in /opt) I've created a basic C++ (STL) library using autotools.
My configure.ac is very simple: <code> AC_PREREQ([2.60]) AC_INIT([exemple], [1.2.3], [t...@exemple.org]) AC_CONFIG_SRCDIR([Makefile.am]) AC_CANONICAL_HOST AC_CONFIG_MACRO_DIR([m4]) AM_INIT_AUTOMAKE([foreign]) LT_PREREQ([2.4]) LT_INIT dnl Check for progs AC_PROG_CXX AC_SUBST([LIBEXEMPLE_SO_VERSION], [1:2:3]) AC_OUTPUT([ Makefile ]) </code> Then I've made a basic OE recipe to build it: <code> SUMMARY = "Libtool simple exemple" LICENSE = "MIT" LIC_FILES_CHKSUM = "\ file://${COREBASE}/LICENSE;md5=3f40d7994397109285ec7b81fdeb3b58 \ file://${COREBASE}/meta/COPYING.MIT;md5=3da9cfbcb788c80a0384361b4de20420 \ " PR = "r1" SRC_URI = "git://xx.xx.xx.xx/libexemple.git" SRCREV = "HEAD" S = "${WORKDIR}/git" inherit autotools </code> Works fine but resulting .la files (in libexemple-dev package) contains: dependency_libs='/opt/...-linux-gnueabi/lib/libstdc++.la' This is bad because if another program (using libtool) depends on libexample, libtool will search libstdc++ in "${STAGING_DIR_HOST}/opt/...-linux-gnueabi/lib/libstdc++.la" (instead of "${STAGING_DIR_HOST}/lib/libstdc++.la"). I would like that dependency_libs points to openembedded sysroot. Note: Toolchain's .la files located in ${STAGING_DIR_HOST} are correct (and not referencing /opt). I am wondering what is the best workaround for this. For now I've patched my recipe: <code> do_compile_prepend () { cd ${S} sed -i -e '/^compiler_lib_search_dirs=/s/.*/compiler_lib_search_dirs=""/' ${HOST_SYS}-libtool sed -i -e '/^compiler_lib_search_path=/s/.*/compiler_lib_search_path=""/' ${HOST_SYS}-libtool sed -i -e '/^sys_lib_search_path_spec=/s/.*/sys_lib_search_path_spec=""/' ${HOST_SYS}-libtool } </code> Ugly but works because libstdc++ can be found (using --sysroot argument). But "dependency_libs" is empty is .la file. In real life: this is libglu and glew. Regards, Matthieu Crapet PS: "exemple" is french word for "example" ;)
