lightning stops building

[renepickhardt]

I don't know why but our current master stopped building even in a clean environment and after running make clean the issue seems to be tool/mockup.sh: line 11: ;;`

I have no clue at all why it stopped working and I am not that deep into the build process of c code.

so even in a completely fresh git clone I run into this issue after ./configure and make

operating system is mac-os. I can later check on a linux machine but I guess if the problem was there too you would already know.

tools/generate-wire.py --page impl tools/test/gen_test.h test_type < tools/test/test_cases > 
tools/test/gen_test.c:
tools/mockup.sh: line 11: syntax error near unexpected token `;;'

    lightningd: check bitcoind version when `setup_topology`

[renepickhardt]

actually on linux I have

tools/generate-wire.py --page header common/gen_status_wire.h status < common/status_wire.csv > common/gen_status_wire.h
Traceback (most recent call last):
  File "tools/generate-wire.py", line 24, in <module>
    from mako.template import Template
ModuleNotFoundError: No module named 'mako'
common/Makefile:83: recipe for target 'common/gen_status_wire.h' failed
make: *** [common/gen_status_wire.h] Error 1
rm external/libwally-core/src/secp256k1/libsecp256k1.la

indicating that a pythong dependency for the tests is missing. was able to fix this with
pip install mako will open a PR in 1 minute in which I add the mako dependency to tests/requirements.txt

other than that on ubuntu lighting builds so I guess it is a mac issue and thus probably harder to fix

Indeed, looks like a Mac issue. Maybe Mac is using a faked bash. Can you try:

ls -la `which bash`

[rustyrussell]

Mako is now a global dependency; it's in doc/INSTALL.md. If you didn't have it, you might have got empty files: try make distclean?

Putting it in requirements.txt for tests/ is a bit misplaced, but can't hurt.

I checkted that file right now and I only found a reference in the ubuntu build instructions but not for mac-os and in the beginning with the global dependencies it was also not mentioned.

I also ran into the missing mako issue when trying to make 0.7.2. Probably good to mention in the release notes.

[gabridome]

I run the same in 0.2.1.

Linux 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u2 (2019-05-13) x86_64 GNU/Linux

make distclean doesn't solve.

I do have mako==1.0.14 in requirements.txt. Trying to setup mako.

pip3 install mako
make clean
make distclean
./configure
make

collect2: error: ld returned 1 exit status
make[1]: *** [tools/test/gen_test.c.tmp] Error 1

further up in the output:

checking consistency of all components of python development environment... no

  Could not link test program to Python. Maybe the main Python library has been
  installed in some non-standard library path. If so, pass it to configure,
  via the LIBS environment variable.
  Example: ./configure LIBS="-L/usr/non-standard-path/python/lib"

   ERROR!
   You probably have to install the development version of the Python package
   for your distribution.  The exact name of this package varies among them.

I have tried to remove mako and check the version.

pip3 uninstall mako

  Successfully uninstalled Mako-1.1.0

ahaa.
wrong version.
I tried also sudo pip3 install -r tests/requirements.txt
but I got the same result.

BTW. It could be related to #2962?

UPDATE: I have checked out master and my problem has disappeared. This make me think that it was related to #2968
