Splint (http://www.splint.org) is a tool for statically checking C programs for security vulnerabilities and coding mistakes. It is a great tool for developers to improve their code with rules stricter than the compiler's ones (even gcc with -Wall). The short story about this port I compiled it years ago on MorphOS and recently I tried to port it to OS4. I was not totally convinced by this quick and dirty port but some days later Tcheko told me I've just ported splint 3.1.2 for MorphOS. I was pleased to see an update for MorphOS too and I was motivated to improve the OS4 port. So we started to talk with Tcheko, about our work and also about a common release. -- Corto-- Yes, MorphOS and OS4 developers can work together to bring better sofware, it was already the case with SQLite. We did separate archives but please consider them as a common port ! Compilation (what I did) AmigaOS 4 is seen as UNIX when there are ifdef. Modified files in directory src/ : - Headers/osd.h : Changed the path separator, the temporary dir - llmain.c : fixed the detection of file ".splintrc" - osd.c : here are the major changed but that's logical, this is the source related to OS dependant stuff - Makefile : added "-lm -lunix" in places where there was "-lfl" Standard installation (recommended) - Copy "splint" and ".splintrc" in "SDK:Local/C" - Create the directory "SDK:Local/share/splint" - Copy directories "lib" and "imports" into it - Define a CPATH setenv which indicates the system includes path : setenv CPATH "SDK:clib2/include" - Copy ENV:CPATH into ENVARC: Note : I added "-ISDK:Include/include_h" in ".splintrc" Custom installation - Unarchive where you want, let us call it MYDIR (for example "Work:splint") - Set environments variables : LARCH_PATH must be MYDIR/lib LCLIMPORTDIR must be MYDIR/imports - Set them in ENVARC : copy ENV:LARCH_PATH ENVARC: copy ENV:LCLIMPORTDIR ENVARC: - Create CPATH like described above splint also uses the file ".splintrc" if it exists, it defines some rules. I did write some minimal rules that are mandatory, mainly for the parsing of OS headers. For example, it defines these constants : -D__amigaos4__, -D__GNUC__ and -D__PPC__ Launch Here I am explaining how to run splint trying to give you some advices. To run splint in a shell, basically : splint filetocheck.c Note that "-D__amigaos4__" is mandatory for a correct parsing of proto files. The problem is that there are errors like "Function IDOS->Close called with 1 args, expects 2". This is certainly due to interface declarations. If the program does not use explicit interface pointers, the error becomes "Unrecognized identifier: Close". At the beginning I suggest you to add the command parameter "-weak" to set splint in a mode less strict : splint -weak filetocheck.c Limitations - The problem of the number of parameters in function calls - Do not support relative file path with parent directories like "splint //example.c". Just do "cd //" and "splint example.c" or use the absolute path. Fix that would need deeper changes and that's not a big constraint. - Tests on code warnings are almost all good running the whole testsuite ... but it may be right enough for a normal behaviour. There is one spec warning for each test with this message : "LSL signature parsing: can't find file Work:splint/lib/CTrait.syms containing".
