[Coin-discuss] environment variables

[Stephan Hennig]

Hello,

@Laszlo Ladanyi:
Thanks alot for your answer. Osi/ now compiles fine with the OSL
interface enabled. To be as much compliant to your "standards" I
installed OSL within $(HOME)/osl. With the same argument I decided to
try Red Hat because I found that distribution mentioned several times in
the coin-discuss archive.

I'll try to avoid asking basic unix questions here. But isn't RH one of
the most buggy linuxes around? Sorry, no answer necessary.

Thanks for the pointer! Done.

I read that thread but didn't remember it when I run into the same
problem. Thanks! I'll do a new checkout.

Seems I'm constantly running into problems (am I repeating myself?).
This time I tried to make the examples. Making Mkc stopped with some
error complaining BCP_timeout.o could not be found. Making MaxCut rises
the same error. You can find the console output from further make runs
at the end of this mail. As you can see Bcp_timeout.o is touched just
before the linker starts, but I can't find the Junk/ directory. When
searching with Konqueror through the COIN/ directory structure for files
that contain the string 'timeout' Konqueror (repeatingly) quits with an
exception. That's good news when your just searching for another error,
isn't it? I don't want to drive the OS to the limits and I'm *not*
searching for bugs. Do you have any secret hint which Linux distribution
I should try to avoid such messy things? RH already made problems during
installation. The first time it reported hard disk errors that no other
Windows low level program could find (I bought the HD 9 months ago). The
next time RH installed fine without any repair having taken place. I
don't have much confidence to RH.

Sorry, back to BCP_timeout.XXX. Bcp/Makefile contains a part

# Files containing member functions
#BCP_SRC +=	BCP_vector_change.cpp

BCP_SRC +=	BCP_lp_param.cpp
BCP_SRC +=	BCP_USER.cpp
BCP_SRC +=	BCP_timeout.cpp

so I think BCP_timeout.cpp should be located in Bcp/Member . But there
is no such file. There is no such file in COIN/ at all. I asked a friend
 to checkout COIN/ on a Windows machine and he confirmed that he can't
find that source file. What's wrong this time? Do you have any further
hints for me?

Kind regards,
Stephan Hennig


Here's make's console output. Don't wonder about the non-standard
messages. I translated them from german.
