Problem statically linking libraries on OS X

[jimboh]

I have freetype2 and ftgl on my system through MacPorts. I assume that MacPorts compiled them for the architecture of my computer, an Intel-based iMac running OS X 10.6.7.

These are the Linker settings for the CodeLite project:

Append to global settings

Options: -mwindows;$(shell $(WX_TOOL) --debug=yes --libs --unicode=yes);-m32

Library Paths: /opt/local/lib

Libraries: libfreetype.a;libftgl.a;libz.a

All three libraries are in the /opt/local/lib directory.

When I try to build, I get the following errors:

ld: warning: ignoring file /opt/local/lib/libfreetype.dylib, file was built for unsupported file format which is not the architecture being linked (i386)
ld: warning: ignoring file /opt/local/lib/libftgl.dylib, file was built for unsupported file format which is not the architecture being linked (i386)

0 errors, 6 warnings, total time: 00:00:12 seconds

Odd that the messages say "0 errors" after so many problems.

Odd that the first two "ld:" warnings refer to .dylib files when I specified .a files.

The architecture references are odd, since MacPorts presumably built for my system.

What am I doing wrong? How do I fix it? This is driving me nuts!

To be perfectly clear, this is a screenshot of the Linker page of my Project Settings:

Not really codelite related.. but more of wx issue

Some advises:
- Make sure that the wx library you are using is built with wxGL support (OpenGL)
- Try asking your questions in a more wxWidgets oriented forum like: http://wxforum.shadonet.com/

I will follow your advice, but I must ask why I am getting messages about .dylib files being ignored when I specified .a files in CodeLight? That seems very odd.

ld: warning: ignoring file /opt/local/lib/libfreetype.dylib, file was built for unsupported file format which is not the architecture being linked (i386)

I think that this says it all

[jimboh]

but why was the .dylib file passed to gcc when I told CodeLight to use the .a file?

As usual, when asking build problems - the *complete* log should be included (use code tags)

If you would have provided the full log you would have seen the link line that was created by codelite :

Code: Select all

..... -lfreetype .....

Since you are under Mac, I would say that the link has a priority for .dylib over .a (FYI: .so also has priority over .a)
So if the link finds 2 libraries in its path, one with .a and one with .dylib -> it will pick the .dylib one.

If you want to link explicitly against a librarym you should put it in the 'Options' field of the 'Linker' page like this:
if I am reading your Options correct, the line should like similar to:

Code: Select all

-mwindows;$(shell $(WX_TOOL) --debug=yes --unicode=yes)'-m32;/opt/local/lib/libfreetype.a

On OSX 10.6.x, GCC builds 64-bits by default. So likely all your macports libraries are 64-bits

[jimboh]

Thank you, both.

It turns out the problem was conflicting installations of wxwidgets, with part of each in the path and part of each not in the path. MacPorts did this. I had to remove and reinstall both from scratch.

a more wxWidgets oriented forum like: http://wxforum.shadonet.com/

BTW, did that forum move? I haven't been able to access it for several days.
