Hi,

I'm trying to use the pre-builds on Ubuntu 13.04 (rev789 and gcc-or1k-elf-4.8.1-ubuntu-13.04-x86.tat.bz2).

I always get the following error after running �or32-elf-cpp main.cpp�

[start]
/opt/openrisc/or32-elf-1.0rc1-x86/or32-elf-1.0rc1/bin/../libexec/gcc/or32-elf/4.5.1-or32-1.0rc4/cc1plus: error while loading shared libraries: libmpfr.so.1: can not open shared object file: No such file or directory
[end]

Same is true for or32-elf-gcc etc.

Is there anyone who can help me with this ?

Sorry if this question has already been asked, but the openrisc forum is hard to search through.

Thanks a lot in advance,

Cheers, Tobias

At least, I'll try.
Btw, if you tried reading the error message you'll notice that it contains the main idea: 'can not open shared object file: No such file or directory'. I.e. some executable (cc1plus that is part of a compiler) couldn't be loaded because OS failed to find one of its libraries (libmpfr.so.1). One may even remember that this library is required to build and run the [cross-]compiler.
The problem is simple: either you didn't install this library at all/didn't provide right path for it, or you have quite different version of this library in system path.
To solve this problem you can:
1) install the package that provides this file (note: this file is not the only dependency) OR
2) if this file is shipped with prebuilt version of crosscompiler, you should specify LD_LIBRARY_PATH environment variable to point to directories with required libraries OR
3) you can install libmpc-dev + libmpfr-dev + libgmp-dev + possibly some other development packages and build your OWN crosscompiler. That's a good exercise, seriously.

No, it's not hard at all, see my previous message in http://opencores.org/forum,Other,0,5368
For example, https://www.google.com/search?q=libmpfr+site:http://opencores.org/forum gives you a lot relevant of answers.
It's just google'ing skill, nothing more. I hope that it'll help you.

Nable80,

sure, I can read the message. But I was hoping that the pre-build include all the necessary files, and I was hoping that the releases from the oc-team are tested or that reported bugs lead to better pre-builds. I didn't expect to add files, debug, ln, search database etc � With my question I was hoping to trigger a better quality of the releases ;-)

google skills, �, well, based on your link I see that I'm not the only one asking for a search function. I guess it is simple to include this string in a auto-search field on the webpage, without the need to manually add it. I was hoping to trigger this with my thread ;-)

user feedback helps improve quality, �

Cheers, Tobias
