Howdy all! I am a programmer of a free scientific software package, netCDF, used widely in climate science and meteorology.
Recently I managed to get my C library building and testing cleanly on Linux for windows, using mingw32 and wine. This is the greatest idea since sliced bread. (In fact, I would rather live without sliced bread!) But something has recently gone wrong and it is not working for me, due to some libtool confusion on my part, probably. The daily snapshot of the package can be obtained here: ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-4-daily.tar.gz I am building it like this: ./configure -C --disable-dap --disable-netcdf-4 --disable-fortran --disable-cxx --build=x86_64-unknown-linux-gnu --host=i686-mingw32 && make -j check When it builds in the nc_test directory, there is a program (nc_test) which needs to link to the math library. I have AC_CHECK_LIB(m) in the configure.ac, so the math library has been found and added to LIBS. But libtool strips it away! /bin/sh ../libtool --tag=CC --mode=link gcc -g -O2 -o nc_test nc_test.o error.o test_get.o test_put.o test_read.o test_write.o util.o ../liblib/libnetcdf.la -lm libtool: link: gcc -g -O2 -o nc_test nc_test.o error.o test_get.o test_put.o test_read.o test_write.o util.o ../liblib/.libs/libnetcdf.a util.o: In function `dbl2nc': /machine/netcdf/trunk/nc_test/util.c:268: undefined reference to `floor' /machine/netcdf/trunk/nc_test/util.c:278: undefined reference to `floor' /machine/netcdf/trunk/nc_test/util.c:273: undefined reference to `floor' collect2: ld returned 1 exit status As I read the above, when make calles libtool, it has the -lm, but when libtool calls gcc, the -lm is missing. Any idea what I might be doing wrong here? Thanks, Ed -- Ed Hartnett -- e...@unidata.ucar.edu _______________________________________________ https://lists.gnu.org/mailman/listinfo/libtool
