build GCC fails on Debian x64 platform.
build GCC fails on Debian x64 platform.
My platform is Debian x64, the posted tools are for x86 hense I follow the procedure to build myself the toolchain for x64.
Everything goes well and I can complete build gdb and binutils, when building gcc the “make all-gcc” runs for a long time and finally stops at this:
In file included from ../../../source/gcc-4.9.2-20150423/gcc/cp/except.c:1013:0:
cfns.gperf: In function ‘const char* libc_name_p(const char*, unsigned int)’:
cfns.gperf:101:1: error: ‘const char* libc_name_p(const char*, unsigned int)’ redeclared inline with ‘gnu_inline’ attribute
cfns.gperf:26:14: note: ‘const char* libc_name_p(const char*, unsigned int)’ previously declared here
cfns.gperf: At global scope:
cfns.gperf:26:14: warning: inline function ‘const char* libc_name_p(const char*, unsigned int)’ used but never defined
Makefile:1060: recipe for target ‘cp/except.o’ failed
make[1]: *** [cp/except.o] Error 1
make[1]: Leaving directory ‘/home/eddie/Downloads/rl78/build/gcc/gcc’
Makefile:3935: recipe for target ‘all-gcc’ failed
make: *** [all-gcc] Error 2
This is the source code for toolchain for RL78 from gcc-4.9.2-20150423_rl78_v15.02.tar.bz2
However exactly the same problem happens when building the toolchain for RX from gcc-4.8.4_rx_v15.02.tar.bz2.
I traced the issue to cfns.h and took the liberty to change a couple lines to just let the build process continue:
#ifdef __GNUC__
#ifdef __GNUC_STDC_INLINE__
__attribute__ ((__gnu_inline__))
#else
__inline
#endif
#endif
const char * libc_name_p (const char *, unsigned int);
Now the build continues for a long time but ultimately fails with another error (this time the error is different for RX than for RL78), at this point I rather not introduce more changes to I’m reporting it.
Note: I can use the x86 pre-built toolchains -in fact I’m using them – but I thought it’d be important to bring this matter to your attention so you can take a look and fix the conflict in next builds.
Thanks
I downloaded the gcc-4.8.4.201803-GNURX-ELF.run file from the gcc-renesas.com site and changed the permissions to allow it to execute, but I keep getting the error message “No such file or directory”. I am on a 64 bit machine running Ubuntu 18.04.2. How did you get the .run file to run on your Debian machine? Where did you download your .run file?

Hello,
Please let us know, how are you attempting to execute the installer after assigning it executable rights?
Thank you,

sure 😀 Without doing “+x” I will not being able to execute it. Without the dot-slash the error is not any strange to me 
I try another way. I install this: apt install lib32ncurses5 lib32z1
After doing it the “No such file or directory” error did not come again and the “.run”-file was executeable. I think, this is not a mainstream error, because many people install some multilib-stuff and the packages above are still installed.
On other Linux distributions you got a “32bit ELF not executable” or “wrong architecture” or something similar.

Thank you very much for sharing your solution with the rest of the users of our toolchains! We are happy you were able to find the solution eventually.
As you may guess, with the various Linux distributions, and their highly different package repositories, it is quite difficult to ensure full compatibility with all such platforms, which is why we always appreciate any feedback from users that can explain how they were able to install the toolchains with no issues. We thank you for that, and hope other users will find this useful as well.
Should you have any other questions or concerns, please feel free to let us know at any time.

On 64-bit Debian, installation of these packages resolved the issue with gcc-8.3.0.201904-GNURX-ELF.run :
sudo apt-get install libc6-i386
sudo apt-get install lib32stdc++6
By the way, why there is no official Debian package for the toolchain?
-
Thank you for sharing the solution that you have found!
To answer your question, we are currently considering the possibility of an official Debian package for the toolchain. Once a decision has been reached, we will announce it on our website.

I am also attempting to build for the RX and get the same failure when I build gcc. I am using Ubuntu 18.04 LTS and would like to either build my own or find a compatible pre-built toolchain for the RX and other Renesas families. Can anyone provide a solution to the gcc failure?

Hi, on my side, I just gave up trying to build the toolchain because for each issue fixed many more showed up.
However my Debian x64 system was able to take the pre-build toolchain for x32. Just executed the .run installer. I haven’t had any problems using the toolchain since then. I’m sorry for been unable to provide more help but since that solved my problem and I was in the rush to complete my project I didn’t dig in more. -
Thank you @edge30 for the comment. Yes, that’s correct, to install the toolchain, please download the “.run” file, change its permissions to include executable rights (e.g. $ chmod +x
) and then execute it directly.
HI. I am running a “fresh” Debian on a 64 bit machine. I try to run the gcc-4.8.4.201803-GNURX-ELF.run file and get “No such file or directory”. That strange error mostly occurs, if the run-binary does not fit to the system.
It is true, that the “.run” executable is 32bit only?
Will it run, if I install some special multilib packages?

Hi,
Thank you for reaching out!
Could you please verify that:
a) you have executable permissions enabled for the file? If not, please assign them as follows: $>chmod +x gcc-4.8.4.201803-GNURX-ELF.run
b) you are executing the installer as: $>./gcc-4.8.4.201803-GNURX-ELF.run
c) do you still get the same error when attempting to run the installer as above?Please let us know and we would be happy to assist the best we can.

Hello,
Thank you for bringing this to our attention.
We have a dedicated page with build instructions for the RL78 platform, available at https://gcc-renesas.com/wiki/index.php?title=Building_the_RL78_Toolchain_under_Ubuntu_14.04
The instructions above are also working for the Ubuntu 14.04 x64 platform. Would you mind telling us if this is something you had used when attempting the build?
