libqxt compilation - mingw32-make exception

Question

I have a following problem with compiling libqxt.

configure.bat generates files, but displays some warnings:

c:\Users\Lukasz\Downloads\libqxt-libqxt-7e0d3396b765>configure.bat

   Makefiles generated. Run mingw32-make now.

mingw32-make interrupts almost immediately with an exception:

c:\Users\Lukasz\Downloads\libqxt-libqxt-7e0d3396b765>mingw32-make
mingw32-make: Interrupt/Exception caught (code = 0xc00000fd, addr = 0x421963)

The source were downloaded from an official website. Running configure and mingw32-make is the way of compiling that is described in README file. What's wrong here?

Answer 1

The answer was simple and unexpected - mingw32-make has big problems with parenthesis ( "(" signs ) in PATH environment variable. The solution is to remove from the PATH all directories that contain "(".

One can change PATH locally in the command line (while not changing it for any other programs) using syntax: set PATH=..., e.g. my sanitized PATH was:

set PATH=C:\QtSDK\mingw\bin;C:\QtSDK\Desktop\Qt\4.8.0\mingw\lib;C:\QtSDK\Desktop\Qt\4.8.0\mingw\bin\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;

As for getting the current PATH value, use syntax: echo %PATH%.
