Lighttpd

Installing Lighttpd from source with SCons on Alpine Linux fails when SCons searches for the available Lua versions and Lua 5.4 is not installed:

Searching for lua: lua5.4 >= 5.0
Package lua5.4 was not found in the pkg-config search path.
Perhaps you should add the directory containing `lua5.4.pc'
to the PKG_CONFIG_PATH environment variable
Package 'lua5.4', required by 'virtual:world', not found
AttributeError: 'OSError' object has no attribute 'message':
  File "/usr/local/src/lighttpd/SConstruct", line 586:
    if autoconf.CheckParseConfigForLib('LIBLUA', "pkg-config '" + lua_name + " >= 5.0' --cflags --libs"):
  File "/usr/local/src/lighttpd/SConstruct", line 150:
    if not self.CheckParseConfig(*args, **kw):
  File "/usr/local/src/lighttpd/SConstruct", line 144:
    print(e.message, file=sys.stderr)

You can use the attached Dockerfile to reproduce the error.

I don't know the cause of the OSError – I guess pkg-config behaves differently on Alpine Linux than on other operating systems – but with a simple patch (see attached sconstruct-oserror.patch) I was able to install Lighttpd successfully.

• Lighttpd 1.4.58
• SCons 3.1.2
• Python 3.8.7
• pkgconf 1.7.3
• Alpine Linux 3.13
• Lua 5.3
• Docker 19.03.9

PS. Please feel free to use the patch.
