I compiled nss on FreeBSD platform, and wrote a program .
My program use function SECU_ReadDERFromFile, like this
#include "secutil.h"

rv = SECU_ReadDERFromFile(&certDER, inFile, PR_TRUE);
......
This function is in libsectool.a
#nm libsectool.a |grep SECU_Read
00001290 T SECU_ReadDERFromFile
when I compile my program, it can generate .o file. but can't make
executable file. error message like this:

int)'
gmake: *** [certool] Error 1
I try other functions in libsectool.a which is defined in secutil.h. it also
can't been use. I feel so despondent.
Why?? I have already include header file(secutil.h). Anyone can give me some
suggestions? Please help me.
Your link command line looks correct. We link our
command-line utilities with ./lib/libsectool.a instead
of -L./lib -lsectool, but -L./lib -lsectool should work.
Since you use g++ to link, I suspect that you also GetDNToDB.o
is compiled from a C++ file. Try include secutil.h in an extern "C"
block like this:
extern "C" {
#include "secutil.h"
}
Note that libsectool.a is for NSS internal use. So
you are using it at your own risk.
