Dear All,
Now the doc mpir-2.7.0.pdf is loading (Firefox); turning off the virus
scanner was not changing anything.
One further question: As I wrote, the gcc compilation now works fine for
me; however, I would like to call it from Matlab using mex files, and
there, the compiler complains that it does not see any ".lib" files (when
compiling with "mex ... -lmpir" it looks for a file "libmpir.lib") .
Neither do I see any in the MPIR directories.
Should such files be there after a successful installation? Or do I have to
set build options differently? Thank you.
Details and settings:
Mex compile command (in Matlab command line):
"mex -IC:/MPIR/mpir-2.7.0/ -LC:/MPIR/mpir-2.7.0/.libs/
-LC:/MPIR/mpir-2.7.0/mpf/.libs -LC:/MPIR/mpir-2.7.0/printf/.libs mexlib.cpp
myfile.cpp",
where mexlib.cpp is the mex-file (interface to c code) and myfile.cpp uses
some basic mpir commands (init, set, clear). Both files are in
C:/MPIR/mpir-2.7.0.
Compiler answer:
"myfile.obj : error LNK2019: unresolved external symbol __imp___gmpf_init
referenced in function "void __cdecl myfile(double)" "
