-Lgc library not found

[bhelyer]

GC is the Boehm garbage collector. It's probably not installed by default with OS X, so it really should be mentioned on our readme. I don't use OS X myself, so I can't give you specific installation instructions but hopefully an Apple-using compatriot will be along if you need specifics.

I used these commands to create a working libgc.a.

curl http://www.hboehm.info/gc/gc_source/gc-7.4.2.tar.gz -o gc-7.4.2.tar.gz
tar xfv gc-7.4.2.tar.gz 
cd gc-7.4.2
git clone git://github.com/ivmai/libatomic_ops.git
./configure 
make -j9
cp .libs/libgc.a <somewhere where volta can find it>

I personally just install it in a 'lib' folder and point volta to it with:

-L
<path>/lib

OK, thanks ! Now it finds the GC lib (at least, doesn't complain about not finding it).
BUT : I get make: [run] Error 42 (ignored). What is it ?

[Dav1dde]

This means it works! make run compiles and runs the test.volt file (which happens to exit with error code 42). You now have a fully functional Volt compiler! :)

[perfaram]

42... should've guessed ! Thanks again !

One more thing : how do I build it manually ?

[Wallbraker]

Add the following file as volt.conf next the binary (proably in the Volta repo) and edit if needed:

# This is a comment
#
# One argument per line, a whole line is read unescaped.
#
# Replacer variables.
#   %@execdir%  directory where the binary is located.
#   %@arch%     architecture of the current target.
#   %@platform% platform of the current target.
#
--stdlib-file
%@execdir%/rt/libvrt-%@arch%-%@platform%.bc
--stdlib-I
%@execdir%/rt/src
--stdlib-file
%@execdir%/../Watt/libwatt-%@arch%-%@platform%.bc
--stdlib-I
%@execdir%/../Watt/src
-L
%@execdir%
-l
gc
-l
dl

With that config file you will need to checkout the Watt repo next to the Volta repo and then build it.

We hope to add more documentation and howto's in the coming weeks.

You can join us on IRC in #volt on Freenode. And also feel free to checkout our Trello board for some of the plans: https://trello.com/b/tnuM8Sjy/volt

One more thing which isn't documentated, how to build Tesla and Watt:

You either need the Volt compiler in your $PATH or an environment variable called VOLT to link to the ready Volt binary, for me it is: VOLT=../Volta/volt. E.g.: VOLT=../Volta/volt make.

OK, will see that this evening. BTW, #7 .

[perfaram]

OK, everything seems good, everything works, everything compiles, everything is beautiful 😄
