preprocessing cpp file

Hi,
if I try right mouseclick 'Preprocess' in the Workspace view I get the following error:
- ----------Build Started--------
C:\WINDOWS\system32\cmd.exe /c ""mingw32-make.exe" -j 1 -f "lcdsim.mk" ./Debug/lcdcomsource"
----------Building project:[ lcdsim - Debug ] (Preprocess Single File)----------
cc Debug/lcdcomsource.o -o Debug/lcdcomsource
process_begin: CreateProcess(NULL, cc Debug/lcdcomsource.o -o Debug/lcdcomsource, ...) failed.
make (e=2): Das System kann die angegebene Datei nicht finden.
I need a little help here.
There is no cc.exe in the /mingw/bin.
There is a cc1.exe in mingw/libexec/gcc/mingw32/4.4.0/.
It looks like this is done by the makefile but I can't find a command like this.
Don't know where it's going wrong here.

Did you touch the build settings of the compiler by any chance? codelite's makefiles are using gcc / g++ by default
Please check under 'Settings -> Build Settings' under gcc / g++ and see in the 'Tools' that the compiler is indeed g++ / gcc and not cc

No, I didn't touch anything there.
Don't know who is calling cc, make?
Under cygwin cc is a symbol link to gcc.
So I copied gcc.exe to cc.exe.
No it works but I got a lot of errors:
- ----------Build Started--------
C:\WINDOWS\system32\cmd.exe /c ""mingw32-make.exe" -j 2 -f "lcdsim.mk" ./Debug/lcdcomsource"
----------Building project:[ lcdsim - Debug ] (Preprocess Single File)----------
cc Debug/lcdcomsource.o -o Debug/lcdcomsource
Debug/lcdcomsource.o: In function `lcdComSource':
D:/Dateien/CrossWorks/icps-sw/src/lcdsim/lcdcomsource.cpp:8: undefined reference to `_imp___ZN12wxEvtHandlerC2Ev'
D:/Dateien/CrossWorks/icps-sw/src/lcdsim/lcdcomsource.cpp:11: undefined reference to `operator new(unsigned int)'
D:/Dateien/CrossWorks/icps-sw/src/lcdsim/lcdcomsource.cpp:11: undefined reference to `wxSerialPort::wxSerialPort()'
D:/Dateien/CrossWorks/icps-sw/src/lcdsim/lcdcomsource.cpp:11: undefined reference to `operator delete(void*)'
D:/Dateien/CrossWorks/icps-sw/src/lcdsim/lcdcomsource.cpp:21: undefined reference to `operator new(unsigned int)'
...
I don't understand the line: cc Debug/lcdcomsource.o -o Debug/lcdcomsource.
I would have expected something like: gcc
-E Debug/lcdcomsource.
cpp -o Debug/lcdcomsource.pp
Looks like you 're trying to preprocess an object file?

Dont mix codelite and cygwin.

This is because you are comiling .cpp file with gcc - you should use g++

Open 'Build settings' select the compiler you are using, and and then select the 'Switches' entry
Under it, make sure that the 'PreprocessOnly' switch is set to '-E ' (with the space)

I don't hope so
But I have cygwin installed and therefore could see the link.

Yes, this is an issue in my project.
For some weired reasons I have C and C++ code intermixed in my project.
Setting gcc as the build tool it compiles with some warnings.
Code: Select all
cc1.exe: warning: command line option "-Wno-ctor-dtor-privacy" is valid for C++/ObjC++ but not for C
What would be the preferred method in CL for a project with C and Cpp sources?
In a makefile I could choose the compiler for each source or group.
Maybe settings for virtual folders would be an interesting option?

Yes, now I get a file with an .i at the end.
I think that's what i wanted, though its hard to read....
Maybe you want to add the -E in the default settings?
Thanks!

The correct fix is in the 'File Types' properties of the compiler, where each file extension has a unique build line.
The problem that currently there is a single macro named $(CompilerName), separating this to $(C_CompilerName) and $(Cpp_CompilerName) is the correct solution

I will

Since only g++ can compiler both, I would choose g++
