How to build?

[TGMM]

Hello, I'm extremely new to the B2 world and I've been wanting to build the boost library using the IAR compiler.
I saw the toolset and I thought I'd give it a try, I have no experience using toolsets (nor B2) mind you.

I've configured my project-config.jam as such:

import option ; 
 
using iccarm : 8.30.1 : "C:/Program Files (x86)/IAR Systems/Embedded Workbench 8.1/arm/bin/iccarm.exe" ; 
 
option.set keep-going : false ; 

And i'm getting the following error: boost/tools/build/src/build\property.jam:811: in class@property-map.find from module object(property-map)@37 error: Ambiguous key

After looking for it for a bit I noticed you encountered the same issue a while ago and posted your workaround in this issue. But the repo with the workaround is not there anymore, so I'm wondering what the solution is.

I'm sorry for bothering you, any help is appreciated. Thanks in advance.

It's been quite a while since I worked with the IAR compiler, but I would be glad to try to help.

It looks like this toolset does not have the code that broke B2 in that issue, so it might be another issue. What version of Boost.Build are you using and on what system? Can you post more of the error output?

So these are the steps I followed
I went to the boost page and downloaded the latest version, which was 1.74.0 (it's now 1.75.0).
I unzipped it, opened the tools folder then the build folder. Then ran the bootstrap.bat with mingw as argument. (.\bootstrap.bat mingw)
I copied the iccarm.jam file to the root folder and to the tools/build folder.
This is the part where I get lost, if I run .\b2 --toolset=iccarm in the tools/build folder I get the following output:

I tried following the guide at the boost repo instead
and modifying the generated project-config.jam with the following:

import option ; 
 
using iccarm : 8.30.1 : "C:/Program Files (x86)/IAR Systems/Embedded Workbench 8.1/arm/bin/iccarm.exe" ; 
 
option.set keep-going : false ; 

and when I run b2 (which generates in the root folder instead of the tools/build one) I get this:

As you can probably tell, I don't know what I'm doing. Thanks for taking the time to read this.

I will try to help you out. However, what you are doing is fairly complicated and will require learning a bit about B2. I have created an (untested) recipe below to get you started.

I would not recommend changing the Boost.Build installation. You should definitely revert back to the standard Boost installation before continuing. You should not have to do that to use the IAR toolset.

I would encourage you to ask questions at the Boost.Build mailing list (https://lists.boost.org/mailman/listinfo.cgi/boost-build). To use B2 more effectively, there is a lot more to learn.

There are a couple of things to note here.

• there should be very few differences between a normal B2 configuration and one using the IAR toolset (that is kind of the whole point)
• IAR ARM compiler builds only for baremetal (<target-os>elf) and for static linking (<link>static)
• The BOOST_BUILD_PATH is used to find the IAR toolset
• a project is independent of the Boost and Boost.Build installation files

Here is a very simple approach that will work. The steps below should get you started. Basically, we just tell B2 where to find boost-build-iar and we set some features properly on the command line. The directories I use below are examples, you will have to set yourself up how you like.

1. Check out boost-build-iar to a directory somewhere on your hard drive (C:\TEMP\boost-build-iar).

git clone https://github.com/tee3/boost-build-iar.git C:\TEMP\boost-build-iar

2. Create a directory for your project somewhere (C:\TEMP\yourproject).

mkdir C:\TEMP\yourproject

3. Switch to that project.

cd C:\TEMP\yourproject

4. Create a simple C file named hello.c with the following contents.

int main () { return 0; }

4. Create a Jamroot to build main.

exe hello : hello.c ;

5. Create a project-config.jam file with the following contents.

using iccarm : 8.30.1 : "C:/Program Files (x86)/IAR Systems/Embedded Workbench 8.1/arm/bin/iccarm.exe" ; 

6. Build the hello program using the desired toolset from the command line. The build products will be located within the bin directory.

C:\TEMP\yourproject> set BOOST_BUILD_PATH=C:\TEMP\boost-build-iar
C:\TEMP\yourproject> b2 toolset=iccarm=8.30.1 target-os=elf link=static

Note that if you run the project as follows without any changes, you will build the native version of hello, also in the bin directory, but with a different path reflecting your default compiler.

C:\TEMP\yourproject> b2

Good luck!
