Some Perl compile options affects ABI and not using them while compiling
our module resulted in non-working build.
Notably on 32-bit Debian 10, Perl is built with -D_FILE_OFFSET_BITS=64
and our module after being compiled without this option caused segmentation
faults in unexpected places.
It's surplus option because the perl executable returns the proper path.
Also the Perl module configure script was cleaned up a bit.
Note that NXT_PERL_LDOPTS already contains the library path.
While it looks nicer without zero 3-rd version number, this should
improve interoperability. Version string can be parsed or used for
sorting. And it is easier to handle and less confusing when there
is constant number of version parts.
Moreover, NPM also expects version format with 3 parts.
So ".0" has already been used in Node.js module version.
By default "npm install" switches to non-privileged user to run package scripts
if it is invoked by root. As a result it may prevent node-gyp from writing to
package directory and break installation of the module.
To disable this switching the --unsafe-perm flag is added.
In most cases it is not needed because Ruby libraries are in the default path.
At the same time, rpath pointing to the default path is prohibited by rpmbuild
on Fedora.
This is related to issue #87 on GitHub.
Since PHP 7, a zend_signal_startup() call is required if the interpreter
was built with ZEND_SIGNALS defined; such a call was added in 3fd76e4ce70a.
However, the zend_signal_startup() export is missing from the PHP library;
as the result, dlopen() fails with the 'Undefined symbol "zend_signal_startup"'
error while loading the PHP module.
Meanwhile, if PHP is built without ZTS, the zend_signal_startup() call can
be omitted; otherwise, the missing call causes segmentation fault.
The PHP fix already was committed to upstream, but we still have to deal
with numerous unpatched versions remaining at large.
See the related PHP bug: https://bugs.php.net/bug.php?id=71041
Use double quotes to quote a string with the backslash/newline pair.
Newer gmake versions, such as GNU Make 4.1, do not remove the backslash
from a string quoted with single quotes, which results in an extraneous
backslash passed to the shell and, eventually, to the Go compiler.
Configuration and building example:
./configure
./configure python
./configure php
./configure go
make all
or
./configure
make nginext
./configure python
make python
./configure php
make php
./configure go
make go
Modules configuration options and building examples:
./configure python --module=python2 --config=python2.7-config
make python2
./configure php --module=php7 --config=php7.0-config
--lib-path=/usr/local/php7.0
make php7
./configure go --go=go1.6 --go-path=${HOME}/go1.6
make go1.6
