Compiling OpenBSD code

[WeakSauceIII]

I'll try and be as brief as possible. I have read the page on compiling openbsd on openbsd.org. I am doing this so I can compile certain programs with debugging symbols and then source debug them with ddd / gdb. I start by going to /usr/src/sbin/echo for example and then 'make'. I add the -g to the Makefile so it includes debug info when compiling. Certain files such as ifconfig do not link.


root@/usr/src/sbin/ifconfig :make
cc -O2 -pipe -DINET6 -c ifconfig.c
ifconfig.c:102:26: netmpls/mpls.h: No such file or directory
ifconfig.c: In function `setifwmm':
ifconfig.c:1427: error: storage size of `wmm' isn't known
ifconfig.c:1431: error: `SIOCS80211WMMPARMS' undeclared (first use in this function)


I assume the search path for make/gcc is configured somewhere in the bsd.*.mk files. Anyone know how to 'make' ifconfig' for example w/out having to type out the paths for all dependencies?

It looks like you're trying to compile -CURRENT on -RELEASE.. (or an earlier -CURRENT..).

MPLS is a feature that was just recently added, clearly those headers are not on your system..

[WeakSauceIII]

That header exists. If i add the whole path to the ifconfig.c file it will find it and I can run mkdep w/out a problem but the other errors still happen. What you said makes sense though. I will try and get the right code. I'm still interested as to where the path is configured for finding those headers but i have ordered a few used books on make and gcc so I'll find out eventually.

BSDfan666 is correct. MPLS changes to ifconfig(8) were checked in for the first time in early in May, so it appears you were attempting to build -current on a non-current system. You should study Section 5.3 to find the appropriate upgrade path for whatever version you have installed:

http://openbsd.org/faq/faq5.html#BldBinary

If you do have 4.3-release installed, you can upgrade to 4.3-stable by using the OPENBSD_4_3 tag found in CVS. This is further described in Section 5.3.3:

http://openbsd.org/faq/faq5.html#BldGetSrc

Note if you are wanting to play with MPLS, you will only be able to do so in -current.

[WeakSauceIII]

You are the man. I checked out the src again with the -rOPENBSD_4_3 option and it compiles fine.
