Betreff: Re: [CMake] Predownload
Don't you need the toolchain to be configured (Aka project() called) before ExternalProject? You wouldn't be able to update it after the download./FlorentOn Apr 17, 2017 11:18 PM, "Craig Scott" <craig.sc...@crascit.com> wrote:Actually, ExternalProject could even be used to download and unpack the toolchain files in a superbuild arrangement too. Probably makes more sense now that I think about it, since it provides unpacking as well, not just downloading and has a much richer set of download methods.On Tue, Apr 18, 2017 at 8:16 AM, Craig Scott <craig.sc...@crascit.com> wrote:One option may be a superbuild arrangement (based on ExternalProject, online searches should give you details). The only thing the top level would do is setup the sub builds, including downloading and selecting which toolchain(s) to use for each sub build.On Tue, Apr 18, 2017 at 8:03 AM, Florent Castelli <florent.caste...@gmail.com> wrote:It is possible.Nothing prevents you from calling execute_process to download as extract your toolchain file when it is run. You probably want to check the destination folder for a pre existing download though.If you use file(DOWNLOAD...) for downloading the toolchain files and you specify an EXPECTED_HASH, this will also conveniently take care of only downloading the file if it isn't already present. Shouldn't need to resort to execute_process() to do the download.Then, you proceed on configuring Cmake to use it as usual./FlorentOn Apr 17, 2017 14:11, "Zabel, Oliver" <oliverza...@gmx.de> wrote:Hi,
i’m developing Software for embedded Systems and my applications Need to run on different target platforms. Until now we are build our Code with make but i’d like to Switch to cmake. ATM we’re putting our Compiler toolchains in our VCS to be able to produce the same binarys even after years. Until now, there is only one toolchain include in a Project as svn-external/git submodule. But i want to use toolchain-files with cmake.
Now here is my idea and i’d like to know whether this is possible with cmake.
I have my Project root and in this Folder i’d like to have different toolchain files for different Compilers. I’d like to exclude the Compilers as external.
Now i’d like to build the cmake Cache by calling cmake with the required toolchain file. Is it now somehow possible, to download the required toolchain before the Cache is buidl up? If this would be possible, i could dynamicly choose which toolchain i want to have – would be great for Compiler / unit Tests as well.
Perhaps someone has a better idea to do this or even i using such a System and give me a hint?
Thanks a lot!
Best regards,
Oliver
