How to build HELLO.dll and HELLOEngine.dll for Hello Module in Salome

kevintlam · March 27, 2024, 10:36pm

Hello,

I’m currently attempting to compile the HELLO.dll and HELLOEngine.dll from the source code available in the Git repository. It appears that the CMake files provided for both HELLO and HELLOGUI are configured for generating static libraries (.lib) with the following commands:

Could you confirm if this is the intended setup? Additionally, I’m wondering if there are separate CMake files available specifically for building .dll files.

ADD_LIBRARY(HELLOEngine ${HELLO_SOURCES})
ADD_LIBRARY(HELLO ${HELLOGUI_SOURCES})

if you look at the top CMakeLists.txt file, you can see the presence of BUILD_SHARED_LIBS which ensures that DLL are generated.

Hello NabilG,

I appreciate your prompt response. I’ve successfully generated the SalomeHELLO.sln for Visual Studio and built the solution. However, I seem to be missing the .dll files. Could you please verify this? I’ve attached further details for your reference.

can you confirm that your CMakeLists.txt is the nominal one. This later implements the SHARED library generation: line 57

Hello NabilG,

Yes, the CMakeLists.txt file I am using matches yours. Please see attached.

can you try to follow the recipe described at this link: SF-505

Note that there is no need here to apply the suggested patches.

Hello NabilG,

I successfully followed the attached instructions until the step where it prompted to clone the HELLO and CONFIGURATION. Please see attached error message. The issue derives from the presence of a ‘rm’ command, designed for Linux systems, while I am operating on Windows. Is there a script available that I can adjust to use ‘rmdir’ for Windows?

I extracted the HELLO and CONFIGURATION source manually into the SALAME-9.12.0\W64 folder, followed by executing the compilation command. Here’s the resulting output.

The BUILD and SOURCES folders that were generated remained empty.

Have a look at file named LOGS\HELLO\cmake to see the error message or upload this file.

More generally SAT saves log files in LOGS

Regards.

Here is cmake file in LOG\HELLO folder.

The directory SOURCES\HELLO
Is empty.
You can proceed as follows in a cmd terminal

cd SOURCES
rmdir /Q /S HELLO
git clone https://git.salome-platform.org/gitpub/samples/hello.git HELLO

Then repeat the compile step.

Here is the new cmake file in the LOG\HELLO folder after recompiled:

Either install visual studio communauty 2017.
Or use a more recent one and set cmake generator to the corresponding value.

If installed. Source its setup script as described in reference thread.

kevintlam · April 3, 2024, 6:13pm

I am using Visual Studio 2022 and I am setting the cmake generator and here is the error.

Hi NabilG,

Were you able to successfully build the HELLO.dll and HELLOEngine.dll with provided source code in git repository?

Kevin

NabilG · April 3, 2024, 6:26pm

Here you’re trying to compile by command line.
If you use SAT, edit SALOME-9.12.0(windows).pyconf and fix the cmake generator.
If you aim to do it wirhout SAT, then you need to setup SALOME environment by running call env_launch.bat first.

kevintlam · April 3, 2024, 6:36pm

I tried to do it without SAT so I run env_launch.bat then
PS C:\S> SALOME-9.12.0\W64\Python\python.exe SAT\sat compile SALOME-9.12.0 -p HELLO,CONFIGURATION --clean_all

Is this the expected result?

NabilG · April 4, 2024, 12:22pm

I will give it a try on my side and share the output - later this week.

kevintlam · April 4, 2024, 2:56pm

Thank you, NabilG.

NabilG · April 7, 2024, 1:26pm

Here is what I did:

Install Visual 2017 available at this link
Install git available at this link: Git
download SALOME-9.12.0 and install it on D:\S (you can install it on C:\S)
download script SALOMEConfigTool.bat from this link: SALOMEConfigTool.bat
Start CMD terminal
go to the directory in which SALOME-9.12.0 was extracted, then run (and be patient):
call SALOMEConfigTool.bat --application SALOME-9.12.0 --use-gitpub --products CONFIGURATION,HELLO

This command will:
- clone SAT and SAT_SALOME
- patch SAT_SALOME to remove some non public products
- target gitpub repositories and clone CONFIGURATION and HELLO products
- set up visual 2017 by running:
  call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" x64
You can then check that CONFIGURATION and HELLO are in directory SALOME-9.12.0\SOURCES

compile HELLO module:
SALOME-9.12.0\W64\Python\python.exe SAT\sat compile SALOME-9.12.0 -p HELLO,CONFIGURATION --clean_all

kevintlam · April 8, 2024, 9:27pm

Hello NablG,

Thank you for the detail instructions. I followed your instructions to set it up but I am not getting the same result. Do you know why?
Here is the result I got.

For “Compilation of HELLO”, I got CONFIGURE instead of OK and I only got Compilation : OK (1/2) not 2/2.
