#21533 [Opn->Fbk]: Trouble building PHP w/ GD and including ImageTTFxxx functions

ID: 21533 Updated by: iliaa@php.net Reported By: jeffabruce@hotmail.com -Status: Open +Status: Feedback Bug Type: GD related Operating System: RH 7.2 PHP Version: 4.3.0 New Comment: If you change char *error; to char *error = NULL; does the segmentation fault you are seeing go away? Previous Comments: ------------------------------------------------------------------------ [2003-01-22 13:57:11] jeffabruce@hotmail.com The version of gd.c that I have is supposed to be 4.3.0. I still believe it is incorrect. If you are referring to the statement: Line 2951: #else /* !USE_GD_IMGSTRTTF */ that 'else' is related to a "USE_GD_IMGSTRTTF" and is not the same as any "HAVE_GD_STRINGxxx" defines. I'm saying that if USE_GD_IMGSTRTTF *is* defined, but neither HAVE_GD_STRINGFT nor HAVE_GD_STRINGTTF is defined, it will leave the variable 'error' undefined, and then try to use it (resulting in the possibility of a crash). Do you still disagree? ------------------------------------------------------------------------ [2003-01-21 14:20:13] iliaa@php.net The ifdef is correct, because no matter what the value will be assigned to error. There is another ifdef surrounding this code which has an else condition that is used to set a value to error. So the crash you are seeing comes from elsewhere. ------------------------------------------------------------------------ [2003-01-21 09:28:38] jeffabruce@hotmail.com PHP build: configure --with-apxs=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql --enable-track-vars --with-imap=/usr/local/imap --with-gd --enable-ftp --enable-sysvsem --enable-sysvshm --enable-sockets --with-gettext --with-mm=/usr/local/lib/mm --with-jpeg-dir=/usr/lib --with-zlib-dir=/usr/local --with-openssl=/usr/local/ssl --with-ttf --enable-gd-native-ttf --enable-gd-imgstrttf --with-freetype-dir=/usr/local --with-dom FreeType: freetype-1.3.1.tar.gz was untarred and built and installed with: configure make make install ------------------------------------------------------------------------ [2003-01-20 17:11:22] sniper@php.net What was the configure line ? And exactly what freetype 1.x version was installed? And how? ------------------------------------------------------------------------ [2003-01-20 16:48:08] jeffabruce@hotmail.com I'm really not a Linux developer, and although what you are asking for sounds easy enough, I don't know how to give you what you want. I would like to reiterate that there are 2 issues here: 1. Configure incorrectly reporting my support for FreeType2 2. gd.c has code that given certain #if conditions, leaves the variable 'error' undefined. The crash is occuring because of the reference to this floating pointer. I assume you want a backtrace to determine the line of code that is crashing, but I'm *giving* you the line of code that is crashing. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
