I notice that SC/MrC checks for foo.h in the current directory, fails to find it, then checks in inc and finds it. MWC68K/MWCPPC starts the same way but after failing to find it in the current directory it gives up; it doesn't check anywhere else.
The current directory is the implicit first directory to search. If I run MWC68K/MWCPPC with -cwd explicit -i inc
to tell it to search only the directories I specify (and not to search the current directory) then it works. If I specify another bogus include directory first (-cwd explicit -i wrong -i inc
) then it again only looks in the first specified directory and doesn't look in the second directory where it would have found it.
I wonder if this comment in OS::FSMakeFSSpec
(in toolbox/os_highlevel.cpp) might be the reason:
// todo -- if the file does not exist (but the path is otherwise valid), create the spec but return fnfErr.
I'm trying to use Metrowerks CodeWarrior MWC68K and MWCPPC compilers with mpw emulator and I'm having trouble getting them to find include files in other directories.
I have a file main.c:
and in a directory "inc" I have a file foo.h:
First, here's MPW's SC (version 8.8.4f1) and MrC (version 4.1.0f1c1) compilers (from MPW 3.5) handling this successfully:
Interesting that the directory name must end with a slash, but I can deal with that.
Next, here's CodeWarrior's MWC68K and MWCPPC compilers (version 2.3, from CodeWarrior Pro 5) failing to handle it:
Interesting that if I specify a nonexistent include directory, MWC68K/MWCPPC prints a warning about that:
So since that warning is not printed when using the "inc" directory it is finding the "inc" directory but is for some reason still unable to deal with it.
MWC68K/MWCPPC is able to find include files that are in the current directory.
I tested in MPW 3.5 on a Power Mac G3 running Mac OS 9.2.2. There, the syntax appears to be that the directory name must be preceded by (and may be followed by) a colon (i.e.
-i :inc
or-i :inc:
). There, all four compilers were able to find the include file in the directory.Running in mpw emulator, SC and MrC also accept the
-i :inc
or-i :inc:
syntax, but MRC68K and MRCPPC still are "Unable to resolve alias foo.h".Toolbox trace
