[edit] μMPS Installation

[edit] mips/mipsel-linux-gcc

If you fall in a error like this: 

configure: error: *** mips-linux-gcc not found in /usr/local/bin

or obviously: 

configure: error: *** mipsel-linux-gcc not found in /usr/local/bin

Then there's a configuration issue about the path to your cross-toolchain. If you still have not builded it, then you need to do it now. If you have it installed, then you need to specify (if it's path is different from /usr/local/bin) the absolute path to the cross-compiler binary (mips-linux-gcc or mipsel-linux-gcc). Look here for more informations.

[edit] libforms.so.1: cannot open shared object file

If you fall in a error like this: 

make[2]: Entering directory `/home/username/umps-1.23-rc2/support'
./umps-elf2umps -v -b exec
./umps-elf2umps: error while loading shared
libraries: libforms.so.1: cannot open shared object file: No such file or directory
make[2]: *** [exec.rom.umps] Error 127
make[2]: Leaving directory `/home/username/umps-1.23-rc2/support'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/username/umps-1.23-rc2'
make: *** [all] Error 2
[root@localhost umps-1.23-rc2]#

Then your μMPS cannot find a path to your XForms installation. This may happen for three resasons:

  • You still haven't installed them at all
  • You have installed them in a path different from the standard one
  • Your μMPS has been configured to look in a specific path wich isn't where XForms are installed.

For the first case, you have simply to install them.

If you have them already in your system, ss a first option, you can try to instruct μMPS to look at the right place, setting LD_LIBRARY_PATH to include the path to XForms library.

If you use tcsh: 

% setenv LD_LIBRARY_PATH /path/to/FORMS

If you use bash: 

$ export LD_LIBRARY_PATH=/path/to/FORMS"

If you still cannot get out of it, you are strongly encouraged to follow the μMPS Installation Guide.

[edit] does μMPS work over Amd64?

The only way to get μMPS working over an Amd64 is to use a full 32-bit environment (i.e.: install the i386 version of your preferred distribution).
