#19572 [Fbk->Opn]: Compilation fails with undefined reference to `__log1p'

ID: 19572 User updated by: pkett@genesis-midi.com Reported By: pkett@genesis-midi.com -Status: Feedback +Status: Open Bug Type: Compile Failure Operating System: Linux (Suse 6.1) PHP Version: 4.2.3 New Comment: Upgrading gcc to version 2.95.3 has solved the problem. Maybe something should be added to the FAQ to indicate that it won't compile properly on older versions. The version I was using BTW was the version installed with Suse 6.1 not something I added afterwards. Previous Comments: ------------------------------------------------------------------------ [2002-09-24 08:11:39] pkett@genesis-midi.com Can compile other stuff without problems - in fact I upgraded apache on the machine just prior to attempting to compile php. I have just installed gcc 2.95.3 on there and am in the process of retrying php. I'll let you know if that fixes the problem. ------------------------------------------------------------------------ [2002-09-24 06:21:41] sniper@php.net Forgot to ask: Are you able to compile anything else? Do you have the kernel headers links correctly set? ------------------------------------------------------------------------ [2002-09-24 06:20:47] sniper@php.net There might be something wrong (or missing) in your system. Could you try installing GCC 2.95.3 ? ------------------------------------------------------------------------ [2002-09-24 04:16:28] pkett@genesis-midi.com I am attempting to compile PHP under Linux with egcs-1.1.2. If I compile php as a DSO module it compiles fine but apache won't load it complaining of unresolved symbols. If I try and compile it into apache I get the following compilation errors : -o httpd buildmark.o modules.o modules/standard/libstandard.a modules/proxy/libproxy.a modules/php4/libphp4.a main/libmain.a ./os/unix/libos.a ap/libap.a -Wl,-rpath,/usr/local/mysql/lib -rdynamic -L/usr/local/mysql/lib -Lmodules/php4 -L../modules/php4 -L../../modules/php4 -lmodphp4 -lmysqlclient -lz -lcrypt -lresolv -lm -ldl -lnsl -lresolv -lcrypt -lm -lcrypt -lndbm -lexpat modules/php4/libphp4.a(zend_ini_scanner.lo): warning: multiple common of `yytext' modules/php4/libphp4.a(zend_language_scanner.lo): warning: previous common is here modules/php4/libphp4.a(math.lo): In function `zif_atanh': /usr/include/__math.h:426: undefined reference to `__log1p' collect2: ld returned 1 exit status make[2]: *** [target_static] Error 1 make[2]: Leaving directory `/home/pkett/apache_1.3.26/src' make[1]: *** [build-std] Error 2 make[1]: Leaving directory `/home/pkett/apache_1.3.26' make: *** [build] Error 2 I have tried with 4.2.2 and 4.2.3 with the same results - I suspect it's due to using egcs and not a more recent version of gcc but can anyone confirm this? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19572&edit=1
