OK. I found the problem:
3688 execve("/usr/bin/make cleanall", ["/usr/bin/make", "cleanall"], [/* 36 vars */]
<unfinished ...>
3680 <... gettimeofday resumed> {1092386057, 829845}, NULL) = 0
3688 <... execve resumed> ) = -1 ENOENT (No such file or directory)
It is, as I assumed, an error in TProcess. I will look for a fix.
Vincent, the problem is that the ExecVE call gets the complete
TProcess.CommandLine property as the first argument, when it should only get the
binary name. The error is probably in the MakeCommand() line in
process.inc.
