-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Chuck,
Here's yet another interesting case with libtool-2.2: /bin/sh ../../libtool --tag=CXX --mode=link g++ -O2 -pipe -o libfoo-1.2.la -rpath /usr/lib -no-undefined sources.lo libtool: link: rm -fr .libs/libfoo-1.2.dll.a .libs/libfoo-1.2.la .libs/libfoo-1.2.lai libtool: link: g++ -shared -nostdlib .libs/sources.o - -L/usr/lib/gcc/i686-pc-cygwin/3.4.4 - -L/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../.. -lstdc++ -lgcc -lcygwin - -luser32 -lkernel32 -ladvapi32 -lshell32 -lgcc -o .libs/cygfoo-1.2-0.dll -Wl,--enable-auto-image-base -Xlinker - --out-implib -Xlinker .libs/libfoo-1.2.dll.a Creating library file: .libs/libfoo-1.2.dll.a libtool: link: ar cru .libs/libfoo-1.2. sources.o libtool: link: ranlib .libs/libfoo-1.2. libtool: link: ( cd ".libs" && rm -f "libfoo-1.2.la" && ln -s "../libfoo-1.2.la" "libfoo-1.2.la" ) In this specific case, the static library is missing the ".a" extension (Windows ignores the final dot, as usual). Here's why: This package had AM_GNU_GETTEXT in configure.ac without any arguments nor AM_GNU_GETTEXT_VERSION. autoreconf decided "not using Gettext"[1] and didn't install config.rpath[2]. But AC_LIB_RPATH (from the included gettext-0.11.2 lib-link.m4) was called; while nothing happened due to the missing config.rpath, it then defined libext=$acl_cv_libext, which had never been defined. This empty $libext clobbered that of libtool. In this case, the solution was simply to call AM_GNU_GETTEXT_VERSION. But this is the second case where libtool's had its variables clobbered by other parts of configure. Could something be done to make sure that that can't happen? Yaakov [1] autoreconf decided "not using Gettext" because it looks solely for AM_GNU_GETTEXT_VERSION to make that determination. (It only looks for AM_GNU_GETTEXT to see if one of these two is used without the other, and emits a warning if so.) [2] lib-link.m4 0.15 adds a line telling automake >= 1.10 that config.rpath is required, but this package was using 1.9. In any case, this macro was from 0.11.2, which preceded automake-1.10. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Cygwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEAREIAAYFAkgRC2sACgkQpiWmPGlmQSPDkwCfdkU3rN1Ul1YYm6yhebClVyDg Eu0AoO+O803peOIDxLD4RFEKNIWRHvyi =mGuQ -----END PGP SIGNATURE----- -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
