I have in options the path to the simpleserver (now compileserver) set to C:\lazarus\components\pas2js\bin\compileserver.exe on port 3000. If I create a new app, I set in the configfile that a server is needed on port 3000.
Then I put the line writeln('hello') and compile it without errors. Then I run the app without debugging. Nothing happens. When I want to run for the second time, it comes with the errer "file not open"
How can I use simpleserver with pas2js?
-
You can start compilerserver with option -s, then it will behave like simpleserver.
Or you can build simpleserver. Its sources can be found in fpc trunk packages/fcl-web/examples/simpleserver/

Im trying to create a Web Browser Application from New Project.
I setup my global options as on the wiki (https://wiki.lazarus.freepascal.org/lazarus_pas2js_integration#Global_options).
Compiled `fpcsrc\packages\fcl-web\examples\simpleserver` manually and changed path of compileserver from $MakeExe(IDE,simpleserver)
to `C:\lazarus\fpc\3.2.2\source\packages\fcl-web\examples\simpleserver\simpleserver.exe`.
When I run the project I get the following:
Simple Web Server:
Wrong compileserver exe: simpleserver does not support --version, maybe this is an old version?
see Tools / Options / Environment / Simple Web Server / Simpleserver
Where can i find the correct compileserver.exe with --version support?
I'm using Lazarus 3.0 (rev lazarus_3_0) FPC 3.2.2 x86_64-win64-win32/win64 with the latest pas2js main git branch.
Thanks,

The version option was added last year in trunk (see commit (https://gitlab.com/freepascal.org/fpc/source/-/commit/d338206814796306ab4dc428f1a398326ee0a4df)) so you would have to download the sources from trunk and compile it manually to create the (correct) executable.

You are aware the compiler itself can run as cgi? You only need to provide an interface.

I used fpcupdeluxe-x86_64-win64.exe and compiled fpc trunk(lazarus failed see below), I then compiled C:\fpcupdeluxe\fpcsrc\packages\fcl-web\examples\simpleserver using lazarus 3 ide i download from the web. Had to change lazarus Tools > Options > Env, compiler to C:\fpcupdeluxe\fpc\bin\x86_64-win64\fpc.exe and fpc source to C:\fpcupdeluxe\fpcsrc\.
Now I can run "Web Browser Application from New Project".
I had another problem,
c:\prj\pas>pas2js -Jc -Jirtl.js -Tbrowser astar.js
astar.js(1,4) Error: can't find unit "System"
Fatal: Compilation aborted
I added -vt to pas2js for more verbose config debugging and realised the pas2js.cfg is broken for package directory using unix pathing(/) instead of windows pathing(\), changed:
#IFDEF FPC_SUBTARGET_NAMESPACED
-Fu$CfgDir\..\..\packages/*/*/namespaced
-Fi$CfgDir\..\..\packages/*/*/src
#else
-Fu$CfgDir\..\..\packages/*/*/src
To
#IFDEF FPC_SUBTARGET_NAMESPACED
-Fu$CfgDir\..\..\packages\*\namespaced
-Fi$CfgDir\..\..\packages\*\src
#else
-Fu$CfgDir\..\..\packages\*\src

No, want to give a example? Was just following the docs on pas2js on the wiki,

Thank you,
You're welcome :)
I used fpcupdeluxe-x86_64-win64.exe and compiled fpc trunk(lazarus failed see below), ....
You must have had the worst timing ever :-X
This issue was closed a couple of hours ago so if you try to compile trunk again then the particular issue for which you posted the error-log, should be fixed now. BTW thank you very much for posting the error-log as it make things more clear about what exactly you are dealing with. Also thank you very6 much for the other hints and tips.
