CB ignores search directories/Global variables

[eb]

Googled it and scoured this site for a couple of days.  Now I'm asking.

Why is it that when I "#include rpc.h" the compiler always throws me a "error: rpc.h: No such file or directory"?

My search directories (compiler) are:
  ..\..\..\usr\x86_64-w64-mingw32\sys-root\mingw\include
  C:\cygwin\usr\x86_64-w64-mingw32
  C:\cygwin\usr\x86_64-w64-mingw32\sys-root\mingw\include

My BuiltIn fields are:
  base: C:\cygwin\usr\x86_64-w64-mingw32\sys-root\mingw
  Include: C:\cygwin\usr\x86_64-w64-mingw32\sys-root\mingw\include

My Selected compiler is Cygwin GCC

My rpc.h file is: C:\cygwin\usr\x86_64-w64-mingw32\sys-root\mingw\include\rpc.h

Did you try turning on full compiler logging and reading the build logs?

http://wiki.codeblocks.org/index.php?title=FAQ-Compiling_%28errors%29#Q:_How_do_I_troubleshoot_a_compiler_problem.3F

Edit: You do know that you are still likely mixing Cygwin and MinGW headers and this is likely NOT to work.

All the Build Log shows is this:

-------------- Clean: Release in rap00 ---------------

Cleaned "rap00 - Release"

-------------- Build: Release in rap00 ---------------

Compiling: main.c
In file included from C:\cygwin\home\eb\rap00\main.c:10:
C:\cygwin\home\eb\rap00\rap.h:10:17: error: rpc.h: No such file or directory

C:\cygwin\home\eb\rap00\main.c:47: warning: unused variable 'Pclient'
Process terminated with status 1 (0 minutes, 0 seconds)
2 errors, 2 warnings

I was under the assumption that I set something wrong and need to be pointed to the proper setting.

Also, I'm trying to use only the mingw headers/libs that came via the cygwin installer. 
I'm hoping they already have a facility for this problem.

I suggest you also read my response in the cboard forum; which I am guessing was started by you.

http://cboard.cprogramming.com/c-programming/145288-undefined-reference-clnt_create.html

Feel free to keep the Code::Blocks questions in this thread; but, I think the root cause of your problem is a Compiler question that is not correct to post this forum.

Thanks Tim.  Didn't see that last post over there until now.

And in my defense my original question over here is (basically):
  What is the proper CodeBlocks setting so that when I #include <rpc.h> the compiler looks for C:\cygwin\usr\x86_64-w64-mingw32\sys-root\mingw\include\rpc.h?

A a related problem/question is:
  If you look at my settings (see previos reply) why is it that #include "tirpc/rpc/clnt.h" leads me to C:\cygwin\usr\include\tirpc\rpc\clnt.h when I do not have "C:\cygwin\usr\include" entered as any of my settings.  I did before but as you see I have removed them AND restarted CodeBlocks.

Again I apologize for the elementary question but the online manual has me befuddled.

"And another thing!..."

This may help someone figure out what i'm doing wrong:
  If I add "C:\cygwin\usr\x86_64-w64-mingw32\sys-root\mingw\include\rpc.h" to the project, I can right click-> Open #include file: 'rpc.h' and it with open the proper file but the compiler still can't find it.

fyi - I have Compiler logging: set to Full command line.
My other 2 choices are 'Task description' and 'No logging'.

That can be true; but, if you do NOT post the full build log after a full rebuild; then it really does NOT help us help you.

Edit: You do realize that you are likely wasting your time. Getting MinGW64 headers to work with the Cygwin compiler is NOT easy and may be impossible!!

Tim S.

[eb]

That may be so but my immediate problem is getting Code Blocks to work properly.
For instance I have just changed my Compiler logging setting from 'Full command line' to 'No logging', I executed a 'Rebuild workspace' and the build log says the same EXACT thing it said  before.
  It seems to me that CodeBlocks is saving my settings as I can see them from session to session, but it's not using them.

  And I am happy to lay off of the non-CodeBlocks issue BUT it does not make sense to me that Cygwin would supply Mingw libs that you could not use with Cygwin.

NOTE: The Compiler you are changing the options on; MUST be the Compiler you are using to compile your project!

To check the CB Compiler name being used to compile your project do this.
"Project" -> "Build Options"
Check the selected compiler for each of the Target in the left hand pane.

To change Compiler Options:
"Settings" -> "Compiler and Debugger"
Pick the correct Compiler in the "Selected Compiler" pull down.
NOTE: Making this the default compiler is recommended!

Well under my Global compiler settings my Selected compiler says Cygwin GCC.
Auto-detect set the Compiler's installation directory to C:\Cygwin.
Global compiler settings->Toolchain executables->[tab]Program files->C compiler is C:\cygwin\bin\x86_64-w64-mingw32-gcc.exe .

[eb]

So i tried starting from scratch.
I started a new project with a new name.
Main.c and rap.h are both in the C:\cygwin\home\eb\rap02 directory.
I have also entered 'C:\cygwin\home\eb\rap02' into Search directories->[tab]Compiler (under Global compiler settings).
The Selected compiler is still Cygwin GCC.

So now main.c contains '#include rap.h' and with Compiler logging set to Full command line my Build log says:



-------------- Build: Debug in rap02 ---------------

x86_64-w64-mingw32-gcc.exe -Wall  -g    -IC:/cygwin/home/eb/rap02  -c C:/cygwin/home/eb/rap02/main.c -o obj/Debug/main.o
cygwin warning:
  MS-DOS style path detected: C:/cygwin/home/eb/rap02/main.c
  Preferred POSIX equivalent is: /cygdrive/c/cygwin/home/eb/rap02/main.c
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:
    http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
C:/cygwin/home/eb/rap02/main.c:10:17: fatal error: rap.h: No such file or directory
compilation terminated.
Process terminated with status 1 (0 minutes, 0 seconds)
1 errors, 0 warnings

[eb]

OK you win.  I'm switching back to non-cygwin headers/libs BUT this codeBlocks problem is still a problem!

[stahta01]

Under Compiler Settings "Other Settings"
Check-mark "Explicitly add project top-level directly to compiler search dirs"
Note: The one above this might be more correct. I sometimes check mark them both.
