gnat2why FSF build fails - "Ada_Text_IO_Child" is undefined

[steve-cs]

Within the last few days updates to GCC/master appear to have broken the FSF build of SPARK2014. I believe the only change to my nightly build at that time was updated ./gnat2why/gnat_src. Should the spark2014/fsf branch be following gcc/master or gcc/releases/gcc-10 at the present time?

Hello,

Thank you for reporting this issue. We just synchronized the fsf branch to the GCC sources at the FSF. Please let us know if you still have build issues.

@pmderodat Broken in a different place.

Hello again @steve-cs,

My mistake: in order to synchronize the fsf branch and the GCC sources, I used git commit date, whereas I should have used the merge date instead. This should now be fixed, sorry for the inconvenience!

gnat2why, gnatprove now build. So that looks to be the end of gcc version problems. But I run into a different problem towards the end of building why3 that I haven't seen before.

FYI.

make[2]: Leaving directory '/home/steve/gnat-builder/spark2014-build/why3'
mv ./why3/bin/why3.opt ./install/libexec/spark/bin/why3.opt
mv: cannot move './why3/bin/why3.opt' to './install/libexec/spark/bin/why3.opt': No such file or directory
Makefile:84: recipe for target 'why3' failed
make[1]: *** [why3] Error 1
make[1]: Leaving directory '/home/steve/gnat-builder/spark2014-build'
Makefile:708: recipe for target 'spark2014' failed

I don't think this is my problem, but I'm not sure. I'll track this down later and open a different issue unless you want to look at it first. No hurry.

Thanks!
