LFS live CD 6.5 chapter 6.14. MPFR-2.4.1 make check 2 errors


Well, things were going too smooth I guess

I'm a little concerned because the book says when you check everything MUST go smooth. When I make mpfr-2.4.1 and do a check I get the following:

Code:
a lot more code above this

What is this? I'm a litle afraid that things went wrong at compiling zlib, there was a note in the book that I didn't understand

Quote:
Note

Zlib is known to build its shared library incorrectly if CFLAGS is specified in the environment. If using a specified CFLAGS variable, be sure to add the -fPIC directive to the CFLAGS variable for the duration of the configure command below, then remove it when building the static library.
what is CFLAGS and how do I add the -fPIC directive to ./configure? I tried a lot of syntaxes but always I get something like unknown option...

You could try setting the CFLAGS temporarily like the comment stated. try this

e.g.
Code:
export CFLAGS="-fPIC" && ./configure 
make
make test
make install
unset CFLAGS
This set a global CFLAG for GCC of "-fPIC" its a frame-pointer... for more information on CFLAGS read these.

http://forums.remote-exploit.org/bt4beta-howtos/21764-gcc-optimisations-cflags-cxxflags.html


http://en.gentoo-wiki.com/wiki/Safe_Cflags

As an alternative to this, read the README or INSTALL and look for the configure option to add custom CFLAGS to the ./configure

Or... if you send me your specfic cpu type, and I can set you up with some safe global GCC build flags to put into your .bashrc file.

Its overly complicated, whenever your building source.

Well, don't tell me I threw myself in the adventure and it's even harder than expected . But I learned a lot about "what makes linux tick" so far, I think I have a long way to go

Really thanks lot! A great piece of advice man! And good links, now I have an idea what I'm doing and have to do with the CFLAGS. I was thinking how or where to export it, some textfile??? Nope a lot easier

No problem ... I have been where your at ... If your interested in adding package management to your LFS, I'm writing a blog piece that adds Arch's pacman and ABS to your LFS install. Its almost complete, should be finished shortly.
