I am trying to get allegro 4.3 SVN to build, so that I can try and make a patch to fix a possible bug http://www.allegro.cc/forums/thread/591107. I have sed ('GNU sed version 3.02') and sort ('sort (GNU textutils) 2.0') from http://unxutils.sourceforge.net/ installed

I installed mingw using the following packages

binutils-2.15.91-20040904-1.tar.gz
gcc-core-3.4.2-20040916-1.tar.gz
gcc-g++-3.4.2-20040916-1.tar.gz
mingw-runtime-3.9.tar.gz
mingw-utils-0.3.tar.gz
w32api-3.5.tar.gz
dx70_mgw.zip

I used SVN to get the newest WiP and did the following

fix mingw
make depend
misc\fixdll.bat
make

It gets all the way up to the dlltool part, then it goes bad.

My errors are:

I have attached my lib/mingw32/allegro.def file just in case it will be useful.

I can't find anything recent that explains how to solve the problem, and it seems everyone who has had this problem was with much earlier versions of allegro.

I'm not sure what to try next

Hi, I made 4.3.1 just today. However, it will probably be easier for you just to make a patch against the 4.2 branch.

I have created a patch that will work with both with 4.2 and 4.3 and its in this post http://www.allegro.cc/forums/thread/591107/667363#target

Edit:

I tried compiling 4.2 SVN in the same way, and got exactly the same errors. Still not sure of the problem.
