Well, it seems that changing all bools to ints doesn't help. It still work with
C but not with C++.
I changed bools to ints and recompiled the library.
Then I copied xdrfile_c_test.c, headers and the recompiled library to the
separate directory.
gcc -c xdrfile_c_test.c
gcc xdrfile_c_test.o libxdrfile.a -lm
After that I have functional text program.
Now, I tried to make a test with C++ with this simplest program:
#include "xdrfile.h"
#include "xdrfile_xtc.h"
int main(){
XDRFILE* xd = xdrfile_open("a.xtc","r");
int n;
read_xtc_natoms("a.xtc",&n);
}
g++ -c test.cpp //Works fine
g++ test.o libxdrfile.a
test.o: In function `main':
test.cpp:(.text+0x38): undefined reference to `read_xtc_natoms(char*, int*)'
collect2: ld returned 1 exit status
I'm completely and absolutely lost now... Any ideas?
