HashLink output not working

[varomix]

Hi
I'm trying to compile to native using HashLink and I can't make it work
I'm using Ubuntu 17.10, Haxe 4.0.0.preview.3 and HashLink 1.5

I can compile to C but compiling using GCC throws a bunch of errors and fails
commands
haxe -hl output.c -cp src -lib heaps -lib hlsdl -main Main
gcc -o myapp -I. -D INCLUDE_ALL -std=c11 output.c -Lhl

https://pastebin.com/MNcKBRpX

also compiling to .hl works but running that throws another error
haxe -hl output.hl -cp src -lib heaps -lib hlsdl -main Main
hl output.hl src/module.c(296) : FATAL ERROR : Invalid signature for function sdl@gl_options : Piiiii_v required but Piiiiii_v found in hdll
I'm following compilation instructions from here: https://hashlink.haxe.org/

So basically can't make it work in any way, please help

thanks

your sdl.hdll is outdated, and you want -lhl not -Lhl. you'll also want the hdlls in your build (i.e. gcc -o myapp output.c -I. -lhl -lSDL2 sdl.hdll ui.hdll). set LD_LIBRARY_PATH to the location of the up to date hdlls if it still doesn't work (LD_LIBRARY_PATH=. ./myapp)

Hi
thank you for that
I built HashLink from Git so I think they should be up to date

well something different happened, but is still not building
I got this error now
gcc -o myapp output.c -I. -lhl -lSDL2 sdl.hdll ui.hdll
/usr/bin/ld: /tmp/ccM9HboN.o: undefined reference to symbol 'fmod@@GLIBC_2.2.5' //lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status

thanks again

[shakesoda]

Add -lm

more errors but seems to me that we're making progress :)
gcc -o myapp output.c -I. -lhl -lSDL2 -lm sdl.hdll ui.hdll

output to big see it here please

per the function signatures, this time you need fmt.hdll -lopenal -lGL

[varomix]

not there yet but close
gcc -o myapp output.c -I. -lhl -lGL -lSDL2 -lm -lopenal sdl.hdll ui.hdll fmt.hdll openal.hdll ui.hdll uv.hdll

bad link order, put -lGL later

[varomix]

had it all over the place, is not working

gcc -o myapp output.c -I. -lhl -lSDL2 -lm -lopenal -lGL sdl.hdll ui.hdll fmt.hdll openal.hdll ui.hdll uv.hdll

same output

[varomix]

Ok fixed the GL issues by putting the libs after the hdlls

gcc -o myapp output.c -I. sdl.hdll ui.hdll fmt.hdll openal.hdll ui.hdll uv.hdll -lhl -lSDL2 -lm -lopenal -lGL
now I get this

/tmp/cc8amjjA.o:(.data.rel+0x5dc8): undefined reference to sdl_create_cursor_from'
/tmp/cc8amjjA.o:(.data.rel+0x5dd0): undefined reference to sdl_create_system_cursor' collect2: error: ld returned 1 exit status

thank you

It finally works, had to use hsdl that comes with hashlink
haxelib dev hlsdl path/to/hashlink/libs/sdl

that was quite a challenge :)

[Justinfront]

Varomix If you get a chance it would be good if you can summarise the steps you needed.

[varomix]

In summary I used

• Haxe 4.0.0-preview.3
• Heaps from git repo as well
• Compiled Hashlink from github
• used hlsld from that same code source haxelib dev hlsdl path/to/hashlink/libs/sdl

to compile, which I did on Kubuntu 17.10, installed the dependencies, GCC, SDL, OpenAL, OpenGL etc.
then to compile I used this commands

To generate the C source
haxe -hl output.c -cp src -lib heaps -lib hlsdl -main Main

To compile the native app
gcc -o myapp output.c -I. sdl.hdll ui.hdll fmt.hdll openal.hdll ui.hdll uv.hdll -lhl -lSDL2 -lm -lopenal -lGL

order of those options are REALLY important, have all those libs after the *.hdll

and that should work, I only did this on Linux so, windows and Mac would be a bit different

let me know if there are any issues

Good luck.

[Justinfront]

I asked on behalf on all users. I will try again but probably not at the moment.

[Doppp]

I actually have this issue on Windows. I tried linking my hlsdl to the one in the HashLink source like @varomix but it still breaks for me.

[ncannasse]

Fixed, please update haxelib hlsdl library for hashlink 1.5 usage

• Haxe 4.0.0-preview.3

I did all the same but using https://haxe.org/download/file/4.0.0-preview.5/haxe-4.0.0-preview.5-linux64.tar.gz/ and on Arch Linux. Linker still complains:

/usr/bin/ld: /tmp/ccUzUUfH.o:(.data.rel+0x80c0): undefined reference to `sdl_win_destroy'
/usr/bin/ld: /tmp/ccUzUUfH.o:(.data.rel+0x80c8): undefined reference to `sdl_set_vsync'

I've set haxelib dev hlsdl ~/dev/hashlink/libs/sdl pointing to my hashlink installation directory.

Also I use this params to compile:

gcc -o main main.c -I. -lhl -lSDL2 -lm -lopenal -lGL

...because hdll's are not found if I add them to list:

gcc: error: sdl.hdll: No such file or directory
gcc: error: ui.hdll: No such file or directory
gcc: error: fmt.hdll: No such file or directory
gcc: error: openal.hdll: No such file or directory
gcc: error: ui.hdll: No such file or directory
gcc: error: uv.hdll: No such file or directory

Could that be the reason of undefined references? How to add them properly?

[slouffka]

gcc -o main main.c -I. -L/usr/local/lib sdl.hdll ui.hdll fmt.hdll openal.hdll ui.hdll uv.hdll -lhl -lSDL2 -lm -lopenal -lGL

Still gives the same result.

ls -1 /usr/local/lib 
fmt.hdll
libhl.so
libstlink.a
mysql.hdll
openal.hdll
pkgconfig
sdl.hdll
ssl.hdll
ui.hdll
uv.hdll

export LD_LIBRARY_PATH=/usr/local/lib don't help either.

[ncannasse]

@slouffka try to put all the hdll (+ -L) before main.c, you can also make sure the symbols are part of the hdll by using nm sdl.hdll | grep std_win_destroy

[slouffka]

@ncannasse thanks for the reply. It helped a lot.

nm sdl.hdll still wont find the lib. After some trials and reading man nm I found it wont use the PATH or LD_LIBRARY_PATH even if they set correctly. It just need the full path to object file or to be called in the same directory.

I've created a simple bash script. Could be an inline command but this reads better and can be reused if put in parent of ./out directory. Also turns out there's no matter where to put main.c -o main. You just need to set full paths to *.hdll files.

Now the code is compiling and running well.

I've ended with these scripts to compile:

$ cat compile-hl-c.hxml

-lib heaps
-lib hlsdl
-hl out/main.c
-main Main

and

$ cat compile

#!/bin/sh

haxe compile-hl-c.hxml &&
cd out &&
gcc main.c -o main \
  -I. \
  /usr/local/lib/sdl.hdll \
  /usr/local/lib/ui.hdll \
  /usr/local/lib/fmt.hdll \
  /usr/local/lib/openal.hdll \
  /usr/local/lib/ui.hdll \
  /usr/local/lib/uv.hdll \
  -lhl -lSDL2 -lm -lopenal -lGL
