cc1plus.exe: unrecognized option `-Winvalid-pch'
« on: November 05, 2005, 02:36:09 am »
I'm trying to build Code::Blocks from source. So far I have followed these instructions to the letter
http://wiki.codeblocks.org/index.php/Compiling_wxWidgets_2.6.1_to_develop_Code::Blocks_%28MSW%29


Error:

cc1plus.exe: unrecognized option `-Winvalid-pch'


I searched the web for -Winvalid-pch but couldn't find anything on it. :(

Update to a recent mingw

$ mingw32-gcc -v
...
gcc version 3.4.4 (mingw special)

This should be added to the wiki I guess.

(btw, -Winvalid-pch tells the search engine to look for pages which do not contain "Winvalid-pch".  What you really want is to search google for Winvalid-pch)

Thanks, I updated MinGW and everything seems to be working well now. I'm not quite sure how I ended up getting such an old version since according to the website 3.4.2 has been out for over a year and I installed MinGW less than 6 months ago.

I tried searching for "Winvalid-pch", and "invalid-pch" and was not able to come up with any information on it on google.com or groups.google.com. :(

From the mingw manual, chapter 3.8 (http://gcc.gnu.org/onlinedocs/gcc-4.0.2/gcc/Warning-Options.html#index-Winvalid_002dpch-286)
Quote
-Winvalid-pch
    Warn if a precompiled header (see Precompiled Headers) is found in the search path but can't be used.
Life would be so much easier if we could just look at the source code.
