Unable to build njs with QuickJS support as a module

[woxxo]

When building Nginx with njs as a static module according to this instruction, everything works like a charm:

./configure --add-module=<NJS_SRC_ROOT_DIR>/nginx

I would like to use QuickJS engine, but can't configure the compilation properly, always getting these logs:

configuring additional modules
adding module in /home/opt/src/njs-master/nginx
checking for QuickJS library -lquickjs.lto ... not found
checking for QuickJS library -lquickjs ... not found
checking for QuickJS library -I/usr/include/quickjs/ -L/usr/lib/quickjs/ -lquickjs.lto ... not found
checking for QuickJS library -I/usr/include/quickjs/ -L/usr/lib/quickjs/ -lquickjs ... not found
 enabled webcrypto module
 enabled xml module
 enabled zlib module
 + ngx_js_module was configured

Using these options with precompiled QuickJS libs in the mentioned folders don't give any positive result:

--with-cc-opt="-I/usr/include/quickjs/" --with-ld-opt="-L/usr/lib/quickjs/"

Please provide an instruction how to successfully compile njs supporting QuickJS as a static nginx module!

Hi @woxxo,

checking for tries to compile a certain C file, please, make sure you are using the recent QuickJS library. The last released version is not enough. For details check <NJS_SRC_ROOT_DIR>/build/autoconf.err.

I am going to improve the reporting to make this process more transparent.

After setting PREFIX?=/usr and make && make install for the recent Quickjs downloaded direct from the github repo, the ./configure log has changed:

configuring additional modules
adding module in /home/opt/src/njs-master/nginx
checking for QuickJS library -lquickjs.lto ... not found
checking for QuickJS library -lquickjs ... not found
checking for QuickJS library -I/usr/include/quickjs/ -L/usr/lib/quickjs/ -lquickjs.lto ... not found
checking for QuickJS library -I/usr/include/quickjs/ -L/usr/lib/quickjs/ -lquickjs ... found
checking for QuickJS JS_NewTypedArray() ... found
 enabled QuickJS engine
 enabled webcrypto module
 enabled xml module
 enabled zlib module
 + ngx_js_module was configured

And the resulting nginx executable got +5 Mb in size. I guess the QuickJS library was linked.

But there is another problem now:

nginx: [emerg] invalid value "qjs" in .......conf:5

server {
    js_path ".....";
    js_import main from .....;
    js_import ......;
    js_engine qjs;           <---- line 5

With the line 5 commented out everything works fine, as well as with js_engine njs; set explicitly. How to setup js_engine to use QuickJS in the config file?

[xeioex]

Hmm, it is controlled by the same define, which is defined here. Adding -DNJS_HAVE_QUICKJS=1 to --with-cc-opt= should fix this. But we need to find why it does not propagate.

Ok, it is working now, js_engine can be changed as expected! Thank you!
