Hi,

I'm running pkgsrc on AIX, and PCRE is not compileable with gcc 3.4. I get the
following linking error:

: gmake
gmake all-am

For me it looks like the symbols in libpcrecpp and libpcre are not resolvable.
I tried to find out from which of both libraries the error comes from:

:gcc -o .libs/pcrecpp_unittest pcrecpp_unittest.o -lc -L./.libs -lpcrecpp 2>&1
|grep -E '(is|assert)'
ld: 0706-027 The -R /opt/pkg/gcc34/lib flag is ignored.

ld: 0706-027 The -R /opt/pkg/gcc34/lib flag is ignored.
ld: 0711-317 ERROR: Undefined symbol: .__assert(char const*, char const*, int)

isdigit() ischar() in a C++ program itself works without a problem:

: cat b.c ; c++ b.c && ./a.out ; echo $?
#include <iostream>
#include <ctype.h>
using namespace std;
int main()
{
        int a=1;
        if (isspace(a))
                cout << "foo";
}

ld: 0706-027 The -R /opt/pkg/gcc34/lib flag is ignored.

So - I have no idea why it cannot be linked with. For me it looks like an error
