help with compiler problems...

[Anonymous]

Can't figure out what I did wrong in install. I installed VCToolkit, and MinGw compilers. Imported a Devv-C++ project, but when I try to rebuild all, I get the following message:

Project   : Project2

It's a misconfiguration of the resource compiler, windres.exe.
MinGW's windres option "-I" is now deprecated (can't remember the exact windres version that happened) and "-J" should be used instead. But if your windres chokes on "-J", then just edit it in the advanced compiler options.

The solution is mentioned in this thread.

Thanks, that was helpful, but I've been reading about compiler flags and C++ directives, and link options and whatnot all day. I'm still having this trouble:

Project   : Project2
Compiler  : GNU GCC Compiler (called directly)
Directory : D:\CodingStuff\Isolation Booth\
--------------------------------------------------------------------------------
Switching to target: default
Compiling: component.cpp
C:\DOCUME~1\jessica\LOCALS~1\Temp/cckNbaaa.o(.text+0x2de): In function `ZN10CComponent14QueryInterfaceERK5_GUIDPPv':

Process terminated with status 1 (0 minutes, 2 seconds)
2 errors, 0 warnings

Part of the problem is that there are three places to edit compiler options, that I have found so far. Any help clarifying this would be great.

To correct the two errors above, add a linker option -ldxguid and change the project type to "Console application".
As far as compiler options are concerned, you can change global compiler options ("Settings/Configure plugins/Compiler"), per-project compiler options and per-target compiler options. The last two, are configured in the same window ("Project/Build options") depending on the selected tree branch in that window.
Usually, you would configure per-project and/or per-target options. I 'm not sure why somebody would use the global compiler options but it's there as an option, just in case...
Note that when using per-project and per-target compiler options, you can configure the order in which they are applied.

add a linker option -ldxguid

Err, I meant -luuid  :oops:
