ipe fails to build with new lua 5.3

[m7.thon@…]

ipe requires lua 5.2 and is not currently compatible with lua 5.3. Unfortunately, the lua port has been updated from 5.2 to 5.3, breaking ipe.

A port "lua52" is required to fix this.

[m7.thon@…]

working on a patch to make ipe compile with lua 5.3

[m7.thon@…]

Ok, so this now makes ipe compile with lua 5.3 (and also lua 5.2)

This only required replacing "luaL_checkint" and "luaL_optlong" by "(int)luaL_checkinteger" and "(long)luaL_optinteger", which used to be defined like this by macros, so I do not expect any problems (it seems to run fine from brief testing).

I'll submit the patch upstream as well, but it may take a while for the new version to appear.

Could someone please commit (I maintain the ipe port, but have no commit rights)? Thanks.

• New simplified Portfile to allow compilation with lua 5.3
• patch-lua53-compatibility.diff no longer needed

I just realized that it is sufficient to compile with lua 5.2 compatibility mode by defining LUA_COMPAT_5_2 (didn't know that this needed to be explicitly enabled)

I have the same issue as #49085, which was marked as a duplicate of this ticket. It seems that our problem is still unresolved and this ticket should probably not me marked as "fixed", should it? Or maybe the modification sugested in comment 4 hasn't been commited yet?

The patch above worked fine for me. There are currently two bugs while installing ipe. You have to install two patches before do so:

• qt4 patch can be downloaded here: ​qt4-mac.10.11.diff   (​Ticket #48129)
• Lua 5.3 patch can be downloaded here: ​Portfile-ipe.diff  ( ​Ticket #48873)

To submit the patches enter the following commands, but replace PATH_TO (for me it was “~/Downloads/” ):

cd $(port dir qt4-mac)
sudo patch -p0 < PATH_TO/qt4-mac.10.11.diff
cd $(port dir ipe)
sudo patch -p0 < PATH_TO/Portfile-ipe.diff

@louis:

This patch has been committed, as Ryan has stated above, and this issue should be fixed.

Did you do the following?

sudo port selfupdate
sudo port clean ipe
sudo port install ipe

You will need to install qt4-mac first (requiring the El Capitan patch that you need to manually apply, as explained above).

[esperet]

Sorry, I'm confused. The conclusion of Ticket #48129 is that the patch has been commited, so why should I have to apply the El Capitan patch of qt4-mac manually? It is said there that qt4-mac-4.8.7_2 should work fine.

[m7.thon@…]

Yes, you are right. I was not aware that the qt4 patch had been committed. However, qt4 was also reorganized into its own directories to make it no longer conflict with qt5 (another unrelated change), which again breaks ipe. See the new ipe ticket #49192, which has a patch for this as well, but is (as of now) not yet committed.

In any case, this issue (lua 5.3 incompatibility) is fixed.

ok, thank you!
