Hello, It is possible to pass in the gcc command line include directories via -I or -I-. I am faced with a problem that I have too many -I<dir> lines in the gcc command line. It leads to "Argument list too long" error. I am thinking that probably it is possible to put all -I<dir> options in a separate file and pass the file location to gcc. Is it possible at all? Unfortunately I did not find a solution how to implement it in gcc. May be there is some other way how to pass a lot of -I<dir> options without having troubles with "Argument list too long error"? I do not have root access on the host so, cannot "play" with ARG_MAX environment variable. Code refactoring is not a solution at the moment. Thanks in advance for your help, Vasily Lukichev.
