Use of setenv() is not portable

[rkl]

In the FileZilla Client 3.1.6 code, src/interface/locale_initializer.cpp makes a call to setenv(), which unfortunately not every platform has (my example is HP-UX 11.11). To fix this in a somewhat kludgy way, I took the gitsetenv() routine from git's compat/setenv.c and put it in locale_initializer.cpp (I had to cast the malloc() call in the gitsetenv() function to (char *) as well). Whether there's a more elegant solution, I'll leave it up to you (e.g. you could test for setenv() in configure and #ifdef HAVE_SETENV or something, but you'll still need some code for your equivalent setenv() call of course).

Thanks, fixed. Now checking for setenv in configure, falling back to putenv if setenv is not available.

Thanks for the code fix, but there appears be a minor typo in the putenv() section of code. In 3.2.0rc1, this now reads (line 97 onwards):

std::string str("LC_ALL=");
str += locale;
putenv(str.c_ctr());

I suspect that putenv() call should actually read:

putenv(str.c_str());

[codesquid]

What's wrong with it?

[rkl]

The HP-UX 11.11 C++ compiler baulked at the original putenv() parameter (str.c_ctr()) and looking at the code in the setenv() section, it looked like it should be str.c_str() (i.e. "s" instead of the "c" in "ctr"), which did indeed compile OK.

Of course, silly typo. Correct algorithm though.

To quote Knuth: "Beware of bugs in the above code; I have only proved it correct, not tried it."
