PAPI code requires `-ldl` flag to compile successfully

[Anustuv Pal]

I have configured PAPI with (last commit 411c9f94e9522abfd704df97bf490961b4ed9d11)

$ ./configure --with-debug=yes --prefix=$PWD/install
$ make
$ make install

I have a C code main.c

#include <papi.h>
int main(int argv, char** argc)
{
    int retval;
    retval = PAPI_library_init(PAPI_VER_CURRENT);
    PAPI_shutdown();
    return 0;
}

and compiling this program with

$ gcc main.c -o main -I$PAPI_PATH/include -L$PAPI_PATH/lib -lpapi

give the following linking error

/home/anustuv/papidev/papi-AP/src/install/lib/libpapi.so: undefined reference to `dlopen'
/home/anustuv/papidev/papi-AP/src/install/lib/libpapi.so: undefined reference to `dlclose'
/home/anustuv/papidev/papi-AP/src/install/lib/libpapi.so: undefined reference to `dlerror'
/home/anustuv/papidev/papi-AP/src/install/lib/libpapi.so: undefined reference to `dlsym'
collect2: error: ld returned 1 exit status
make: *** [issue49] Error 1

The error gets fixed if compiled with -ldl flag as

gcc main.c -o main -I$PAPI_PATH/include -L$PAPI_PATH/lib -lpapi -ldl

@Anustuv Pal I am not able to reproduce the problem. I am trying on methane. Where did you try this?
