Linux problem

[chopc 0]

Decided to give Energia a try

I installed Energia on both 32 and 64 bit versions of Ubuntu 12.04 , Mimimal problems with the install ( had to rename librxtxSeriasl.so to OLDlibrxtxSerial.so in the 64 bit install to stop it complaining about wrong word length) but on trying to run the "Blink" program I get the following error :-

/home/User/energia/hardware/tools/msp430/bin/../libexec/gcc/msp430/4.6.3/cc1plus: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory

 

Any ideas ?

[jsolarski-backup 22]

do you have libmpc.so.2 and does it have the right permisions?

I have seen this kind of error when moving shared libraries or if they have the wrong permissions

libmpc.so.2 is present in /usr/lib/x86_64-linux-gnu with all users having read permissions

The next release of Energia is going to include an updated compiler. However, you can find it here now:

 

https://github.com/energia/Energia/blob ... 32.tar.bz2

 

You will have to download and extract that into the appropriate directory on your unpacked Energia directory.

 

The gcc version in that tar file has the FRAM BSL corruption patch installed. Also, it was built with the intent of using fewer external shared libraries by statically linking with some of the required system libraries. If all else fails, you can try the build script located here:

 

https://github.com/energia/Energia/blob ... ild-mspgcc

Since I'm running an old distribution and the bundled binaries require a newer glibc, I used that script and (after installing all required dependencies) it worked. I had to use the mspdebug in the binary distribution (the script didn't build it).

Hello

 

I'm having the same problem. I've tried the above solutions, but I still get the same error message as in your first post.

 

I may have done the script incorrectly. Where should I put it when executing it?

Afraid I can't help , never managed to get Energia running on Ubuntu so I gave up and went to the "Darkside" :- Windows XP , I have an old laptop for some of the many "Windows only" bits of software :-)

I haven't tried Energia on Ubuntu myself, so this is more a general Ubuntu answer than being Energia specifik. Ensure that the libmpc2 package is installed. If the problem persists try setting the LD_LIBRARY_PATH environment variable to point to the location of libmpc2. To do that open a console and type "export LD_LIBRARY_PATH=/usr/lib", replacing /usr/lib with the location of the file. Next, run Energia from that same console.

 

That should do the trick.

There are two options.

 

1.) replace the /installdir/hardware/tools/msp430 directory under Energia with your newly built tools. Where /installdir is the directory where Energia was extracted.

 

2.) rename or delete the /installdir/hardware/tools/msp430 and add the bin path of your newly built tools to your PATH before starting energia.

FOR UBUNTU-12.04 32 BITS.

The file /usr/lib/libgmp.so.3 it's broke, for to solve this problem is necesary to install this library:

 

sudo ln -s /usr/lib/x86_64-linux-gnu/libgmp.so.10.0.2 /usr/lib/libgmp.so.3

sudo apt-get install libgmp3c2

then

sudo apt-get update

 

 

that's all.

Thanks, crow1982, that's got my Energia so it will compile sketches (I'm on Ubuntu 12.04/32-bit). However, I still can't deploy to the MSP430 as I have no serial ports listed, so there seems to be something else needed from stock Ubuntu 12.04/32bit, but I don't know what - any ideas?

I answered my own question... I did try installing some additional libraries based on another page, then saw that the the one did the debugging as root - I then tried running Energia as root, and I had the necessary options in the menu and it's all working.

I'M SORRY BY NOT ANSWER BEFORE, IN MY COMPUTER ENERGIA WORKS GOOD, MAY BE SOME LIBRARIES FROM ANOTHER ONES PROGRAMS HELP, BUT I'M NOT SURE.
