Bug#823042: Aw: Bug#823042: kdiff3: FTBFS on hurd-i386: error: 'PATH_MAX' was not declared in this scope

[Joachim Eibl]

Hi Andreas,

 

Thanks for reporting.

 

To quickly fix your problem please insert three lines before the declaration "char s[PATH_MAX+1);"

 

#ifndef PATH_MAX
#define PATH_MAX 1024
#endif

         char s[PATH_MAX+1];
         int len = readlink(QFile::encodeName(fi.absoluteFilePath()).constData(), s, PATH_MAX);

 

I know the better solution would work without any usage of PATH_MAX, and I will try to fix it according to:

http://linux.die.net/man/2/readlink

 

Best regards,

Joachim
