I do not believe this to be an issue w/ litespeed but I thought someone else here may have run into this issue. I'm having an issue when compiling php(5.2.6 or 5.2.8) with the litespeed api, that I've never seen before. OS = Cent 5.2 php = 5.2.8 mysql = 5.1.3 lsws & lsapi are most current avail If I configure php without a ./buildconf --force to incorporate the litespeed api, it compiles fine. If I touch ac* , ./buildconf --force, and compile as I've always done in the past without issue, I'm getting an error on compile as follows. Code: checking size of char *... configure: error: cannot compute sizeof (char *), 77 See `config.log' for more details. I seem to have narrowed this down to being an issue w/ the running of ./buildconf. I've tried autoconf213 as well as newest avail for distro autoconf259 w/ the same error in end. I did some digging first and found a few references to gcc and/or c++ being the culprit here. I've installed the most recent available through centos repositories. I also found some people that had this being a library path issue. I'm not confident that either is the case here seeing as it compiles just fine so long as I don't rebuild the config (which I have to, to build the lsapi). Here is the resulting config.log file > config.log Any input/tips on this would be awesome. I'm stumped. Thank you very much!
