Compile CodeBlocks by Cygwin

[PetrPetrov]

Also I have standard Windows distribution of C::B, it shows Windows OS in About dialog.
Note that C::B compiled by Cygwin shows 'Linux' OS in About dialog.

I am trying this Configure Command for wxWidgets (wxGTK) (I am using wx 2.8 SVN Branch)

Code Select Expand


../configure --enable-unicode --with-libjpeg=builtin --with-regex=builtin --without-msw --with-gtk --prefix=/opt/wx/2.8 --enable-monolithic  --disable-universal --without-gtkprint --without-gnomeprint --enable-tooltips --enable-dnd --enable-shared


These options --without-gtkprint --without-gnomeprint helped build in the past using wxWidgets SVN trunk (2.9) .

I am nearly certain "--enable-shared" is required for a wxWidgets able to be used by Code::Blocks.
I decided to try "--enable-unicode" this option because this will reduce the patches needed by Code::Blocks it has about 3 places ANSI code needs fixed the last time I did an ANSI build (about 1 year ago.)
I used "--with-libjpeg=builtin" because two years ago; the version of libjpeg in CygWin caused issues.
I used "--with-regex=builtin" because the other poster in this thread commented out code that using this option might NOT need done.

I got the below displayed before I did make; it is still running make.

Configured wxWidgets 2.8.12 for `i686-pc-cygwin'

 Which GUI toolkit should wxWidgets use?                 GTK+ 2
 Should wxWidgets be compiled into single library?       yes
 Should wxWidgets be compiled in debug mode?             no
 Should wxWidgets be linked as a shared library?         yes
 Should wxWidgets be compiled in Unicode mode?           yes
 What level of wxWidgets compatibility should be enabled?
                                      wxWidgets 2.4      no
                                      wxWidgets 2.6      yes
 Which libraries should wxWidgets use?
                                      jpeg               builtin
                                      png                sys
                                      regex              builtin
                                      tiff               builtin
                                      zlib               sys
                                      odbc               no
                                      expat              sys
                                      libmspack          no
                                      sdl                no


I set CXXFLAGS="-Wno-attributes" before running make to reduce the warnings in hope it speeds up the build. Edit: It made no difference in building. Will try next time setting it before the configure command.

wxWidgets is still building.

The command I plan to try on Code::Blocks boot/configure

./bootstrap
export CXXFLAGS="-DWXMAKINGDLL_SCI -Wno-attributes"
./configure

Sorry, I did not run ./bootstrap never....

wxWidgets is not installed property?

wxWidgets is not installed property?

What is the output of "wx-config --cflags --libs" in your console?

[PetrPetrov]

my output is:

$ wx-config --cflags --libs

I am worrying that problem in my Cygwin system.
It seems that libtool utility always create static libraries.

I have created small test project:
1. Wrote small a.cpp file the following content:

Code Select Expand

__attribute__ ((dllexport)) int fn(int a)
{
  return a + 19;
}

and compile it by libtool (just wrapper for gcc)

Code Select Expand

libtool --mode=compile gcc -shared -c a.cpp

now I am trying to get libtest.dll or libtest.la

Code Select Expand

$ libtool --mode=link gcc -shared -g -O -o libtest.la a.lo
libtool: link: rm -fr .libs/libtest.a .libs/libtest.la .libs/libtest.lai
libtool: link: ar cru .libs/libtest.a .libs/a.o
libtool: link: ranlib .libs/libtest.a
libtool: link: ( cd ".libs" && rm -f "libtest.la" && ln -s "../libtest.la" "libtest.la" )

I have specified -shared option.
What I am doing wrong?

[oBFusCATed]

Hm, then do you have wx.m4 file or something like this where AM_PATH_WXCONFIG or AM_OPTIONS_WXCONFIG are defined?

[PetrPetrov]

Thank you very much!

Now I manually copied wxwin.m4 into local codeblocks source folder, and added

Code Select Expand

m4_include(wxwin.m4)
at begin of configure.in...

However, it does not matter... libcompiler.a is still created...
I think that libcompiler.dll should be created to allow codeblocks.exe to load this plugin and able to create new projects....
Please see my post above about libtool problem.

[oBFusCATed]

Can't help on libtool issues, because I don't understand it, sorry.

IIRC, I followed the steps suggested in URL to get past this error in the past.
http://wiki.codeblocks.org/index.php?title=Installing_Code::Blocks_from_source_on_Linux

I likely did something based on this line.

Bingo!
I have compiled plugins as shared libraries:

[PetrPetrov]

Unfortunately, Code::Blocks does not work properly, I can create new 'Console' project in C++.
But gcc compiler is not invocaled from Code::Blocks.

Any ideas?

P.S.: I have specified paths for compiler toolchain, gcc.exe, g++.exe etc.

Other than the standard answer, no.
http://wiki.codeblocks.org/index.php?title=FAQ-Compiling_%28errors%29#Q:_How_do_I_troubleshoot_a_compiler_problem.3F

What path did you use? A windows or a CygWin path?
Because, I have no idea which is more likely to work.

Tim S.

[PetrPetrov]

Sorry for the long delay.

As I can remember I specified Linux path (like /bin/gcc.exe or like /usr/bin/gcc.exe, /usr/bin/g++.exe etc).
I'll have a chance to compile it again in near future, maybe Cygwin was improved as well as C::B.
