Hello,
Several of us are stumped and hoping someone can help.
I'm getting errors linking to netcdf on AIX using g++ 4.2.0. Things
compile fine, but
I get undefined errors for ANY use of the classes in netcdfcpp.h
(NcFile, NcVar, NcDim, etc...)
To simplify debugging a small test program mimics our errors, so any fix
to the simple test
program below most likely will fix our more complex code link elsewhere.....
#include <netcdf.hh>
int main( int argc, char ** argv )
{
NcFile file("out.txt", NcFile::Replace);
return 0;
}
compile works fine...
setenv OBJECT_MODE 32
g++ -o test.o -g -I/nco/ibm/wx15cp/netcdf32/include -c test.C
or
g++ -o test.o -g -fno-for-scope -fno-exceptions -ffriend-injection
-Wno-write-strings -Wall -DKERNEL_WSIZE=32 -DLINUX_FILES=1
-DALLOW_2_DIGIT_YEAR -DXT_CODE -DFTN_APPEND_UNDERSCORE -D_REENTRANT
-I/nco/ibm/wx15cp/netcdf32/include -c test.C
link has errors...
g++ -v -o test test.o -L/nco/ibm/wx15cp/netcdf32/lib -lnetcdf_c++ -lnetcdf
or
g++ -v -o test test.o -L/nco/ibm/wx15cp/netcdf32/lib -lnetcdf -lnetcdf_c++
gets these errors:
ld: 0711-317 ERROR: Undefined symbol: .NcFile::NcFile(char const*,
NcFile::FileMode, unsigned long*, unsigned long, NcFile::FileFormat)
ld: 0711-317 ERROR: Undefined symbol: .NcFile::~NcFile()
as I mentioned before...
-exact same undefined errors for use of any of the classes in netcdfcpp.h
-using g++ 4.2.0 on AIX
-building 32 bit binary and trying to link to 32 bit netcdf lib....
-exact same errors using netcdf 3.6.3 as well as 4.0.1
Anyone seen this or conquered it?
Thanks for any help. It's much appreciated...
Tom
