Hi, I'm currently experimenting with cross-compiling Guile 2 for Android. https://lists.gnu.org/archive/html/guile-user/2014-06/msg00011.html
I met a weird issue: when configuring guile I get this test: ../configure --host=arm-linux-androideabi --prefix=/usr/src/ndk-shared/sysroot/usr --without-threads [...] configure:15799: checking for libunistring configure:15821: arm-linux-androideabi-gcc -o conftest -g -O2 -I/usr/src/ndk-shared/sysroot/usr/include conftest.c /usr/src/ndk-shared/sysroot/usr/lib/libunistring.so -Wl,-rpath -Wl,/usr/src/ndk-shared/sysroot/usr/lib >&5 /usr/src/ndk-shared/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: /usr/src/ndk-shared/sysroot/usr/lib/libunistring.so: error: undefined reference to 'frexp' collect2: ld returned 1 exit status However, trying to reproduce with a simple project, I get: # http://www.beuc.net/misc/testunistring.tar.gz ../configure --host=arm-linux-androideabi [...] configure:7108: checking for libunistring configure:7130: arm-linux-androideabi-gcc -o conftest -g -O2 conftest.c -lunistring >&5 configure:7130: $? = 0 configure:7140: result: yes I can't figure out why the guile test ends-up with linking the .so explicitely, while my test project uses '-lunistring'. Any leads? Also, if using the .so directly is needed for some reason, do we need to add '-lm' somewhere in gnulib's libunistring test? Cheers! Sylvain
