Re: config.m4 Macros and static libs

So, since I am still stuck with this, does anybody have a useful pointer to some Documentation, how to resolve the issue, or should the M4 Macro be considered broken. Or could someone advise some other place to turn to, where I can find someone, who might be able, to help me work out this issue?

Why would I start digging into the m4 file with the PHP_* Macros, though I am not really familiar with M4. Anyway, it seems the check might work, if there wasn't the second lib as dependency. Here is what I am doing right now:

        PHP_CHECK_LIBRARY($LIBNAME,$LIBSYMBOL,[
                PHP_ADD_LIBRARY_WITH_PATH($LIBNAME, $OMAPI_DIR/lib,

OMAPI_STATIC_LIBADD)

                AC_DEFINE(HAVE_OMAPILIB,1,we have the DHCPCTL lib.[])
        ],[
                AC_MSG_ERROR([dhcpctl lib not found.])
        ],[
                -L$OMAPI_DIR/lib -lomapi
        ])

        PHP_SUBST(OMAPI_STATIC_LIBADD)

Unfortunately dhcpctl needs the omapi lib. Now, config log says: configure:4706: cc -o conftest -g -O2 -lomapi conftest.c -ldhcpctl >&5 /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../lib64/libdhcpctl.a(dhcpctl.o): In function `dhcpctl_object_remove': (.text+0x76): undefined reference to `omapi_message_new' Obviously -lomapi is passed, but yet I get unresolved symbols. Both libs reside in the same system lib path, which means both should be found accordingly. Could this be related to the ordering of parameters passed to gcc?

Dear List, My request is a little arkward, since I am not too familiar with the gnu build tools. I want to write a PECL extension for PHP that exploits the features of a specific lib. Unfortunately the lib is only available as static lib (actually it's two libs - anyhow, this shouldn't change too much). As far as I could gather from the m4 file that defines the PHP_* Macros, the PHP_CHECK_LIBRARY Macro only works for shared libs. What would be

Fail. It doesn't care what your library is as long as it's found. :) Try before you ask? It's not that hard. And if you have actual problem with some errors or something, THEN ask.. --Jani -- PECL development discussion Mailing List (http://pecl.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
