You can get the netcdf daily tarball at: ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-daily.tar.gz To get the most simplified case which has this problem, configure it like this with mingw: ./configure --enable-c-only --enable-shared --enable-dll && make check My library seems to build OK as a DLL. (When I test it with Visual Studio, it works). But my own tests don't build in the case of a dll. The first test program it tries is t_nc.c, and that fails to link because of the atexit error. Here's the link of the library and the attempt to build t_nc: /bin/sh ../libtool --tag=CC --mode=link gcc -g -O2 -o libnetcdf.la -rpath /usr/local/lib -version-info 0:0:0 -no-undefined -Wl,--output-def,.libs/libnetcdf.def attr.lo ncx.lo putget.lo dim.lo error.lo libvers.lo nc.lo string.lo v1hpg.lo var.lo posixio.lo libtool: link: gcc -shared .libs/attr.o .libs/ncx.o .libs/putget.o .libs/dim.o .libs/error.o .libs/libvers.o .libs/nc.o .libs/string.o .libs/v1hpg.o .libs/var.o .libs/posixio.o -Wl,--output-def -Wl,.libs/libnetcdf.def -o .libs/libnetcdf-0.dll -Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker .libs/libnetcdf-0.dll Creating library file: .libs/libnetcdf-0.dll libtool: link: (cd ".libs" && rm -f "libnetcdf.lib" && ln -s "libnetcdf-0.dll" "libnetcdf.lib") libtool: link: ar cru .libs/libnetcdf.a attr.o ncx.o putget.o dim.o error.o libvers.o nc.o string.o v1hpg.o var.o posixio.o libtool: link: ranlib .libs/libnetcdf.a libtool: link: creating libnetcdf.la libtool: link: ( cd ".libs" && rm -f "libnetcdf.la" && ln -s "../libnetcdf.la" "libnetcdf.la" ) make t_nc.exe make[2]: Entering directory `/c/cygwin/home/ed/n3_new1/libsrc' if gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../fortran -DDLL_NETCDF -g -O2 -MT t_nc-t_nc.o -MD -MP -MF ".deps/t_nc-t_nc.Tpo" -c -o t_nc-t_nc.o `test -f 't_nc.c' || echo './'`t_nc.c; \ then mv -f ".deps/t_nc-t_nc.Tpo" ".deps/t_nc-t_nc.Po"; else rm -f ".deps/t_nc-t_nc.Tpo"; exit 1; fi /bin/sh ../libtool --tag=CC --mode=link gcc -g -O2 -o t_nc.exe t_nc-t_nc.o libnetcdf.la libtool: link: gcc -g -O2 -o .libs/t_nc.exe t_nc-t_nc.o ./.libs/libnetcdf.lib -L/usr/local/lib ./.libs/libnetcdf.lib(.text+0x160):crtstuff.c: multiple definition of `atexit' /mingw/lib/crt2.o(.text+0x2b0):crt1.c: first defined here ./.libs/libnetcdf.lib(.text+0x190):crtstuff.c: multiple definition of `_onexit' /mingw/lib/crt2.o(.text+0x2c0):crt1.c: first defined here ./.libs/libnetcdf.lib(.text+0x1c0):crtstuff.c: multiple definition of `__do_sjlj_init' C:/msys/1.0/mingw/bin/../lib/gcc/mingw32/3.4.2/crtbegin.o(.text+0x0):crtstuff.c: first defined here t_nc-t_nc.o(.text+0x1d8): In function `main': c:/cygwin/home/ed/n3_new1/libsrc/t_nc.c:369: undefined reference to `_imp__nc__create' t_nc-t_nc.o(.text+0x237):c:/cygwin/home/ed/n3_new1/libsrc/t_nc.c:372: undefined reference to `_imp__nc__create' ... -- Ed Hartnett -- [EMAIL PROTECTED] _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
