Just some random compilation errors and their solutions.

Random FYI:

Apache is pure C code (ie: you just need gcc).

PHP is C++ code (ie: you need gcc-c++).

PHP Compile Error

Compiling php-5.2.x on Fedora

Problem:

?./configure? error during PHP installation process:

Error Message: configure: error: installation or configuration problem: C++ compiler cannot create executables.

Logs show: gcc: installation problem, cannot exec `cc1plus': No such file or directory.

Resolution:

You're missing the C++ compiler. Install gcc-c++

Fedora Core: yum install "gcc-c++"

Problem:

PHP won't compile.

Error Message:

lex: command not found

checking lex output file root... ./configure: line 3246: lex: command not found

configure: error: cannot find output from lex; giving up

Resolution:

You need the Flex libraries

Fedora Core: yum Install Flex
