SCO also allows you to - specify a C dialect with -Xt, -Xa, -Xc, -Xk and -Xm. These are passed - on to the assembler and linker in the same way that the SCO compiler - does. - - SCO also allows you to compile, link and generate either ELF or COFF - binaries. With gcc, we now only support ELF mode. - - GCC also requires that the user has installed OSS646, the Execution - Environment Update, or is running release 5.0.7 or later. This has - many fixes to the ELF link editor and assembler, and a considerably - improved libc and RTLD. - - In terms of tool usage, we want to use the standard link editor always, - and either the GNU assembler or the native assembler. With OSS646 the - native assembler has grown up quite a bit. Some of the specs below - assume that /usr/gnu is the prefix for the GNU tools, because thats - where the SCO provided ones go. This is especially important for - include and library search path ordering. We want to look in /usr/gnu - first because frequently people are linking against -lintl, and they - MEAN to link with gettext. What they get is the SCO intl library. Its - a REAL pity that GNU gettext chose that name; perhaps in a future - version they can be persuaded to change it to -lgnuintl and have a - link so that -lintl will work for other systems. The same goes for - header files. We want /usr/gnu/include searched for before the system - header files.
