[SOLVED] trying to compile

gearheadgeek · 02-16-2015, 10:01 AM

I am having a problem I have never experienced in many years of slackware use. I am putting Slack 14.0 on a BeagleBone Black (instead of Debian) and have it up and running except that gcc silently fails. By that, I mean it runs cc1 without producing an output file, a complaint, an error message, anything, and stops there. I have installed d/binutils, d/gcc, l/glibc, l/gmp, and l/libmpc. What am I missing?

Let's see the exact error message.

louigi600 · 02-16-2015, 02:20 PM

Are the glibc-solibs installed ?
What do you get if you execute

Code:

gcc -v

That should tell you version, target and how it was compiled.
If you try compiling a really simple thing (like just printing on stdo "hello world") what do you get ? and what's the return code of gcc ? (supposing it silently produced nothing)

As I said, it produces nothing - error message or output.

Yes. Sorry, I missed that when looking back at the tag files, but they are installed.

I was compiling "hello world" and as I said, there is no output - error message or anything. The return code is 1 but I couldn't find anything germane on the web.

If you do this it might give you a hint as to what's wrong with your install ...
Your problem inspired me to look into the compilation process step by step ... you can try this step by step to see where your compilation process is failing (sorry some of the timestamps below are wonky ... I was learning something myself while producing it):

Code:

As I noted in my first post, it stops after running cc1 without producing the .s file in /tmp.

It looks like it preprocessed not sure if it assembled ... try that again and add the "-Wall -save-temps" flags and see if you get <whatever>.s ... but since it's returning 1 I think it's not assembling. Are binutils installed ?

You also need these libraries along with glibc-solibs and gcc itself to use gcc:
glibc
zlib
binutils
glibc-i18n
glibc-profile
glibc-zoneinfo
mpfr
libmpc
gpm

If they are all installed you might want to reinstall them all again (just incase the installation was corrupt):
gcc
glibc
glibc-i18n
glibc-profile
glibc-solibs
glibc-zoneinfo
zlib
binutils
mpfr
libmpc
gpm

Hope I didn't forget anything

Didn't know about -save-temps, but still no output from cc1. I did miss a couple the the libs you list but have another fire to put out at the moment. I will get all loaded and try again. Thanks for the help.

For sake of closure and anyone who might stumble upon this thread, I got the fires extinguished and came back to this. Missing mpfr was the problem. Why gcc silently did nothing without it is beyond me, but after adding it, hello.c compiles and gives the expected output. Thanks very, very much. I never would have found that on my own.

louigi600 · 03-21-2015, 03:14 AM

Too much time went by and I forgot how I got the list ... surely I don't know them off the top of my head and ldd on the pieces required to do the single steps did not get me back the full list ... maybe I googled: Prerequisites for GCC ... it's not specific for Slackware (that might not use ISL) but it gives you an idea of what you might need to get gcc to work right.

Good to know that I was helpful ... you can reward helpful posts by clicking on the "yes" right beside "Did you find this post helpful?"

I naturally tried Google before I came here and found requirements to build gcc but not to run gcc.

Done. Thanks again!

gus3 · 03-23-2015, 11:23 AM

Just my US$0.02:

When I have a complicated process that fails for no obvious, visible reason, I find "strace" very handy. I capture its output to a log, then pick through processes to search for the last fork/exec, and/or first failing exit. That's the first clue to follow.

Additionally, GCC's default error exit code of 1 can be overridden with the "-pass-exit-codes" option, which passes back the highest error code of any sub-process back to the top level.

business_kid · 03-24-2015, 05:50 AM

@gearheadgeek: Head over to the linuxfromscratch.org website and they list the requirements for gcc. They are building from scratch. I presume the language you are compiling changes those requirements. I suggest the chapter 6 list
