Test case: - library foo2 depend from foo1 - program foo depend from foo2 (that depend from foo1) - library foo3 depend from foo2 (that depend from foo1) (test case attached as file bootstrap.sh.gz)
On mingw (cross-compilation) the program foo is linked but library foo3 fail.
Mingw (--prefix=/tmp/test/foo/mingw): 1.1) program foo:$ /bin/sh ./libtool --tag=CC --mode=link i386-mingw32msvc-gcc -g -O2 -no-undefined -avoid-version -o foo.exe foo.o lib2/libfoo2.la
....$ i386-mingw32msvc-gcc -g -O2 -o .libs/foo.exe foo.o lib2/.libs/libfoo2.dll.a /<ABSPATH>/build-mingw/lib1/.libs/libfoo1.dll.a -L/tmp/test/foo/mingw/lib
1.2) library foo3:$ /bin/sh ../libtool --tag=CC --mode=link i386-mingw32msvc-gcc -g -O2 -no-undefined -avoid-version -o libfoo3.la -rpath /tmp/test/foo/mingw/lib foo.lo ../lib2/libfoo2.la
....i386-mingw32msvc-gcc -shared .libs/foo.o ../lib2/.libs/libfoo2.dll.a -L/<ABSPATH>/build-mingw/lib1/.libs -o .libs/libfoo3.dll -Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker .libs/libfoo3.dll.a
.... .libs/foo.o: In function `foo3': ..../lib3/foo.c:6: undefined reference to `_foo1' Similar but on linux (--prefix=/tmp/test/foo/linux): 2.1) program foo:/bin/sh ./libtool --tag=CC --mode=link gcc -g -O2 -o foo foo.o lib2/libfoo2.la gcc -g -O2 -o .libs/foo foo.o lib2/.libs/libfoo2.so /<ABSPATH>/build-linux/lib1/.libs/libfoo1.so -Wl,--rpath -Wl,/tmp/test/foo/linux/lib
2.2) library foo3:/bin/sh ../libtool --tag=CC --mode=link gcc -g -O2 -o libfoo3.la -rpath /tmp/test/foo/linux/lib foo.lo ../lib2/libfoo2.la
...gcc -shared .libs/foo.o -Wl,--rpath -Wl,/<ABSPATH>/build-linux/lib2/.libs -Wl,--rpath -Wl,/tmp/test/foo/linux/lib ../lib2/.libs/libfoo2.so -L/<ABSPATH>/build-linux/lib1/.libs -Wl,-soname -Wl,libfoo3.so.0 -o .libs/libfoo3.so.0.0.0
Common is that when link programs all dep-libs are expanded and passed to compiler as non-installed dependent are with absolute path.
If is linked library direct dependent lib and path to indirect are passed to compiler but indirect library is missing on command line.
