trouble building sage on mac

[Anne Schilling]

Hi,

I am trying to build the latest stable release of sage (master branch) from source on MacOS 10.15.5

and got the following error. Any ideas?

Best wishes,

Anne

Cause pillow finds a broken install of freetype here: /usr/local/lib
(which causes the problem:

/usr/local/include/freetype2/freetype/freetype.h:51:10: fatal error:

'freetype/config/ftconfig.h' file not found)

as well as here: /usr/local/Cellar/freetype/2.10.1
- which should be OK.

Does your configuration build freetype ---something you can see in the
main config.log---
or is it configured to use one of these
(in config.log you'd see "use system package and not install SPKG freetype")

pillow does something crazy, anyway:

thanks. What is the output of

$ pkg-config --modversion freetype2

for you?

Incidentally I found a bug in our spkg-configure.m4 for freetype,
which you might be hitting.

The thing is that
$ pkg-config --modversion freetype2
outputs not something sane, but e.g. for freetype version 2.9.1 it is
22.1.6, for 2.10.2 it is 23.2.17
(which is probably some insane value produced following libtool
versioning rules)
while we check for it to be at least 2.4, oops...

That is to say, if you have a very old freetype found by configure,
it will still be accepted.

to be fixed in https://trac.sagemath.org/ticket/30014 - although it's
not really high priority, as most systems
are sane w.r.t. what freeline versions they have.

[Anne Schilling]

thanks. What is the output of

$ pkg-config --modversion freetype2

for you?

sage anne$ pkg-config --modversion freetype2
9.8.3

[Dima Pasechnik]

this is a very old freetype, older than the needed version 2.4 or
newer. So indeed, you hit the bug
being fixed by https://trac.sagemath.org/ticket/30014

Can you just remove that old freetype from /usr/local (you probably
installed it many years ago and don't need, it just
sits in /usr/local, preventing Homebrew from installing an update
there) and re-install freetype from Homebrew?

after this, please re-run `./configure` followed by `make`
(and post the new config.log again, if it still breaks.)

do you get the same error while building pillow (missing header)? If so, it looks as if you removed the old freetype dylib files, but left headers there.

Also, did you source .homebrew-build-env

before doing ./configure && make ?

As you use libraries from Homebrew, this might be crucial.

you had to delete the installation of freetype in /usr/local/{lib, include, lib/pkgconfig}. 

and after that, (re)install freetype in Homebrew.

Deleting /usr/local/Cellar/freetype 

probably was not a good idea - that is where, I guess, you have a good installation of freetype (which you should uninstall using the brew commands, not just deleting from shell)

But I don't know whether your Homebrew is not too old. Can you do

brew install freetype 

(or is it freetype2) 

paying attention to the version it mentions?

in any case, 

./configure --with-freetype=system 

should force sage to build freetype on its own.

Also, did you source .homebrew-build-env

before doing ./configure && make ?

As you use libraries from Homebrew, this might be crucial.

[Zachary Scherr]

Hi All,

   I just thought I would chime in on the homebrew side of things.  I have freetype installed via homebrew on Catalina 10.15.5 and when I execute

> pkg-config --modversion freetype2

I get back 23.2.17.  Anne seemed to get back version 9.8.3, which means that something is screwy with your freetype.

Some things you could try:

1). If you have already installed freetype via homebrew then you can try

 brew unlink freetype && brew link freetype

2). It's possible that "brew doctor" will pick up on the inconsistencies and will give recommendations as to how to fix it.

Your log file specifically mentioned that the system could not find ftconfig.h.  With freetype correctly installed via homebrew you can do the following:

cd /usr/local/include

ls -l | grep freetype2

and you should see that that folder is symlinked to /usr/local/Cellar/freetype/2.10.2/include/freetype2 which is the folder that actually contains all the freetype header files.

Not sure how much you want to invest in fixing this, but my suggestion would be to head to /usr/local and try to find ftheader.h, which is the header file that defines where ftconfig.h is located.  If you find any ftheader.h file that is not originating from local/Cellar/freetype/2.10.2/include/freetype2/freetype/config/ftheader.h then you should delete it.

[Zachary Scherr]

Also, you might also consider doing something like the following:

> cd /usr

> find -L . -name 'ftheader.h'

you should see the following locations:

./local/include/freetype2/freetype/config/ftheader.h

./local/var/homebrew/linked/freetype/include/freetype2/freetype/config/ftheader.h

./local/opt/freetype2/include/freetype2/freetype/config/ftheader.h

./local/opt/freetype/include/freetype2/freetype/config/ftheader.h

./local/Cellar/freetype/2.10.2/include/freetype2/freetype/config/ftheader.h

notice though that "/usr/local/Cellar/freetype/2.10.2/include/freetype2/freetype/config/ftheader.h" is the real file and the others should all be symlinks of this one.

[Dima Pasechnik]

my working conjecture was that Anne had two conflicting installations
