php-master: init at php-8.4.0.snapshot.c803402-20230907122631 #104

jtojnar · 2022-04-26T19:15:26Z

Currently does not build.

Fixes: #35

The current issue: https://dpaste.org/wDL4A

drupol · 2022-04-28T19:51:59Z

I'm trying to get it to compile and while doing things here and there, I notice something.

In here: https://github.com/fossar/nix-phps/blob/php-master/pkgs/phps.nix#L438, the extension curl is in the list and should be enabled.

When I try to build php-master with nix build --override-input php-src github:php/php-src/PHP-8.1 -L .#php-master, it fails.

Then I check the logs: nix log /nix/store/azipihspd62sqzdlhgyg5y2kyfp81xpx-php-8.1.7.pre+date=20220427181447.drv | grep -i 'curl' | less and I see: checking for cURL support... no.

I have the feeling that the configure flags coming from enabled extensions are not going through.

jtojnar · 2022-04-28T23:35:16Z

The curl thing is the same when building regular PHP (nix build .#php81.unwrapped -L --rebuild). We build extensions separately.

Would you be able to compare the source trees between git and archive?

Weird, but ok.

I succeeded to build PHP, but it fails now when trying to compile the extensions:

What's the battle plan ? What are we trying to figure out?

jtojnar · 2022-04-29T23:28:11Z

The reason the extensions fail is this line:

https://github.com/NixOS/nixpkgs/blob/22fbd632e6aaa0436bcb20045799d41853527116/pkgs/top-level/php-packages.nix#L84

The tarball has all files inside php-${version} directory, whereas everything is in the top-level directory in Git.

I also have this issue in the tokenizer extension:

I found those links that might be relevant:

One possible solution would be to replace AC_PROG_YACC with AC_CHECK_PROG in configure.m4.

jtojnar · 2022-04-30T10:24:33Z

I think this might be due to

php-tokenizer> yacc  /build/source/ext/tokenizer/../../Zend/zend_language_parser.y

notice the empty space after $(YACC). For some reason YFLAGS are not set here:

https://github.com/php/php-src/blob/9e74e58bcf7e31aef563f1ee00b7f0bc17fe3ef2/Zend/Makefile.frag#L16

This is probably the same reason PDO fails:

php-pdo> /nix/store/30j23057fqnnc1p4jqmq73p0gxgn0frq-bash-5.1-p16/bin/bash: line 3: --no-generation-date: command not found

$(RE2C) and $(RE2C_FLAGS) are empty here:

https://github.com/php/php-src/blob/9e74e58bcf7e31aef563f1ee00b7f0bc17fe3ef2/ext/pdo/Makefile.frag#L12

You can build with nix build -L .#php-master.extensions.pdo --keep-failed, which will preserve the build directory:

note: keeping build directory '/tmp/nix-build-php-pdo-8.2.0.pre+date=20220426165801.drv-0'

And then look at the generated Makefile in the extension directory /tmp/nix-build-php-pdo-8.2.0.pre+date=20220426165801.drv-0/source/ext/pdo/Makefile – indeed the variables we want are not defined. Nor is there any mention in the generated configure script.

I guess the issue is we are relying on phpize to generate configure script and then that generating the Makefile:

https://github.com/NixOS/nixpkgs/blob/acfb65116af3ba984d844ddb88ab8cf5759c7888/pkgs/top-level/php-packages.nix#L104

But phpize’s generated configure.ac will not have bison and re2c set up like the hand-written one in php root does:

https://github.com/php/php-src/blob/9e74e58bcf7e31aef563f1ee00b7f0bc17fe3ef2/configure.ac#L164-L165

https://github.com/php/php-src/blob/9e74e58bcf7e31aef563f1ee00b7f0bc17fe3ef2/build/php.m4#L1771

drupol · 2022-04-30T11:36:55Z

Wow. Impressive debug. How do you think we should fix that ?

jtojnar · 2022-04-30T11:51:43Z

Maybe insert the PHP_PROG lines into configure.ac after phpize and then run autoconf?

drupol · 2022-05-29T08:28:04Z

What's the battle plan on this one? Could be a very nice to have :)

jtojnar · 2022-05-29T11:00:24Z

Still stuck on the flex/yacc issue.

drupol · 2023-09-07T13:50:59Z

I can build PHP without extensions:

but as soon as I enabled the tokenizer extension, it is failing with:

I think this might be due to
php-tokenizer> yacc  /build/source/ext/tokenizer/../../Zend/zend_language_parser.y
notice the empty space after $(YACC). For some reason YFLAGS are not set here:

https://github.com/php/php-src/blob/9e74e58bcf7e31aef563f1ee00b7f0bc17fe3ef2/Zend/Makefile.frag#L16

This is probably the same reason PDO fails:
php-pdo> /nix/store/30j23057fqnnc1p4jqmq73p0gxgn0frq-bash-5.1-p16/bin/bash: line 3: --no-generation-date: command not found
$(RE2C) and $(RE2C_FLAGS) are empty here:

https://github.com/php/php-src/blob/9e74e58bcf7e31aef563f1ee00b7f0bc17fe3ef2/ext/pdo/Makefile.frag#L12

I've checked the Makefile of the tokenizer extension and YFLAGS, YACC and RE2C variables are set.

I've compared the zend_language_scanner.l in both versions and they are less-or-more the same. The first failure:

php-tokenizer> lex  -t /build/source/ext/tokenizer/../../Zend/zend_language_scanner.l > /build/source/ext/tokenizer/../../Zend/zend_language_scanner.c
php-tokenizer> /build/source/ext/tokenizer/../../Zend/zend_language_scanner.l:24: bad character: #

correspond to this line:

#if 0

Another thing that I've notice during my research is that when compiling tokenizer with PHP 8.2.9 (which is building fine), the Makefile is not in the extension directory.

At this point, we are blocked, I don't know what I could do to get this working. Do you have any clue?

The solution to this PR was the script genfiles that wasn't run properly.
