Hello,
I'm using Cygwin with HDF 1.8.9. I have build the HDF libs with configure, make
and all libs are *.a / *.la files.
If I build an executable creates the linker an error:
library/build_release/hdf/1.8.9/lib/libhdf5_cpp.a(H5File.o):H5File.cpp:(.text+0x2026):
undefined reference to `_H5Rget_obj_type1'

address 0x4 in section `.rdata$_ZTVN2H58CommonFGE[vtable for H5::CommonFG]'
The linker command is:
g++ -o build/release/executable.exe -fopenmp --as-needed examples/executable.o
-Llibrary/build_release/hdf/1.8.9/lib -lhdf5 -lhdf5_hl -lhdf5_cpp -lhdf5_hl_cpp
I'm using C & CPP interface of the HDF library.
Same code and library under Linux works without any problem
Can anybody help me to solve this linker problem? Thanks
Phil
Hi Kraus,
first, the the C interface of HDF5 is already available as
cygwin package
$ cygcheck -c -d|grep hdf5
hdf5 1.8.9-1
libhdf5-devel 1.8.9-1
libhdf5_7 1.8.9-1
About your problem, on cygwin and on windows in general
the order of linking is important
try
-lhdf5_hl_cpp -lhdf5_cpp -lhdf5_hl -lhdf5
Regards
Marco
