building with cegcc

[Sébastien Lorquet]

Hello all,

First of all i'm sorry if this discussion is not related to this mailing
list.

I'm interested in building QT for wince using cegcc (
http://cegcc.sourceforge.net ) It's based on MinGW, and works with cygwin.

I tried to create a working mkspec directory:
- based on win32-g++
- changing the compiler to arm-wince-mingw32ce-gcc
- importing DEFINES from the wince50standard-armv4i-msvc2005 configuration
- importing libraries from wince50standard-armv4i-msvc2005, then change them
to match what I have in mingw32ce
- copying qplatformdefs.h from wince50standard-armv4i-msvc2005

I can provide the exact files to the ones who want it.

I attemted to build under the Qt command line prompt with the following
configure command:

configure.exe -xplatform mingw32ce -no-vcproj

qmake builds
.pro files are read
all tools are built.

then I type:
set INCLUDE=c:\cygwin\opt\mingw32ce\arm-wince-mingw32ce\include
set LIB=c:\cygwin\opt\mingw32ce\arm-wince-mingw32ce\lib
set PATH=c:\cygwin\opt\mingw32ce\bin;%PATH%
mingw32-make

this gives:

C:\Qt\4.3.2-tp1>

I checked the output of arm-wince-mingw32ce-gcc -v ; this is dued to gcc
that tries to run cc1plus using paths that start with /opt and not
c:\cygwin\opts.

Then I tried to run the same in a cygwin shell, with a clean qt source tree:
$ export QTDIR=/cygdrive/c/Qt/4.3.2-tp1
$ cd $QTDIR
$ export PATH=$QTDIR/bin:$PATH
$ ./configure -xplatform mingw32ce -no-vcproj

and then I get:

Unable to detect the platform from environment. Use -platform command
lineargument or set the QMAKESPEC environment variable and run configure
again
See the README file for a list of supported operating systems and compilers.

cygwin does not seem to be supported.
So I forced the host platform:
$ ./configure -platform win32-g++ -xplatform mingw32ce -no-vcproj
to force a mingw build under cygwin

configure complained that:
Creating qmake...
execute: File or path is not found (mingw32-make)
execute: File or path is not found (mingw32-make)
Cleaning qmake failed, return code -1

so I added a symlink in /bin:
$ cd /bin
$ ln -s make mingw32-make
$ cd $QTDIR

then I restarted configure:
...
Creating qmake...
execute: File or path is not found (mingw32-make)
execute: File or path is not found (mingw32-make)
Cleaning qmake failed, return code -1

But when I run it manually, it works:
$ mingw32-make
mingw32-make: *** No targets specified and no makefile found.  Stop.

renaming the link to ming32-make.exe did not help
copying make.exe to mingw32-make.exe gave:

Creating qmake...
Makefile:143: *** target pattern contains no `%'.  Stop.
Makefile:143: *** target pattern contains no `%'.  Stop.
Cleaning qmake failed, return code 2

Is there a way to configure under cygwin?

I did not try the following yet:
configuring with mingw,
then compiling under cygwin, using the previously generated tools.

Thanks!
