Sccache is a ccache-like tool. It is used as a compiler wrapper and avoids compilation when possible. Sccache has the capability to utilize caching in remote storage environments, including various cloud storage options, or alternatively, in local storage.

how to use sccache for ccv850( or how to add complier type for sccache)? #2138

Open chenx319 opened 4 months ago

chenx319 commented 4 months ago

i use a complier of greenhills(ccv850.exe), a gcc-like complier. i want to use sccache to fasten my build . but it seems sccache not support it.

can you kindly give me some help? thanks!

the detail error as follow:

`D:\CX\SW\ccachetest>sccache ccv850.exe -filetype.c main2.c -c main2.o

If you can, you may rename the ccv850.exe to the gcc.exe if your compiler continue to work.

chenx319 commented 4 months ago

hello @AJIOB ， thanks for you help!

it failed after I rename it . but it seems sccache seems to execute it , so i have to find a new solution .

the detail as follow:

D:\CX\SW\ccachetest>sccache gcc.exe -filetype.c main2.c -c main2.o

AJIOB commented 4 months ago

Is the sccache gcc.exe main2.c -c main2.o works nice?

I cannot find any info about -filetype.c flag for GCC.

Also, are the usual commands ccv850.exe -filetype.c main2.c -c main2.o and ccv850.exe main2.c -c main2.o work without error?

P.S. You can use triple-` at the start and in the end of your pasted logs/code for having the nicer view. More info here

chenx319 commented 4 months ago

@AJIOB thanks again !

ccv850.exe -filetype.c main2.c -c main2.o and ccv850.exe main2.c -c main2.o work without error

I try one :

D:\CX\SW\ccachetest2>dir /b
main2.c

D:\CX\SW\ccachetest2>ccv850.exe  main2.c -c main2.o
ccv850: Warning: file 'main2.o' ignored with these options

D:\CX\SW\ccachetest2>dir /b
main2.c
main2.o

D:\CX\SW\ccachetest2>

I delete main2.o, then try two as follow:

D:\CX\SW\ccachetest2>dir /b
main2.c

D:\CX\SW\ccachetest2>ccv850.exe -filetype.c main2.c -c main2.o
ccv850: Warning: file 'main2.o' ignored with these options

D:\CX\SW\ccachetest2>dir /b
main2.c
main2.o

D:\CX\SW\ccachetest2>

I copy some information about -filetype.c

Manually Setting Input File Types On the command line, use -filetype.suffix to indicate that the next file on the command line has the type appropriate for suffix. For example: ccv850 -filetype.cc hello.i compiles hello.i as if it were a C++ file. To process all C files as C++ files, use the following syntax: cxv850 -dotciscxx files Note that these options should not be used in the Builder.

some other tests:

gcc.exe is a copy of ccv850.exe

AJIOB commented 4 months ago

If you have time, try to check if usual gcc (such as mingw64-gcc) works correctly on Windows.

Looks like we have some problems with it on Windows.

P.S. About -filetype.c: it may be the reason not to cache, because it is not gcc-one P.P.S. What about this one: sccache gcc main2.c -c main22.o and pure gcc main2.c -c main22.o, where gcc.exe is ccv850.exe copy?

AJIOB commented 3 months ago

One more note: if you really have time for implementing support for new compiler, you can refer to the #2045 as an example of it.

if i use gcc, it works correctly

PS: 1 yes , this is not a standard gcc 2 from https://github.com/mozilla/sccache/issues/2138#issuecomment-2020398597 you give a suggestion that rename the ccv850.exe to gcc.exe. I don't rename it , but I copy ccv850.exe to gcc.exe

AJIOB commented 3 months ago

I don't rename it , but I copy ccv850.exe to gcc.exe

A1. Yes. Try not to pass .exe extension for sccache's gcc arg. Maybe it will help you with compiler detection.

Also, try to pass full path compiler argument, such as c:/awesome-compiler/gcc (A2) and c:/awesome-compiler/gcc.exe (A3).

The A letter was used just for referencing, nothing else.

Hi again, @chenx319

Is the question resolved?

still failed , detail as follow

thanks for your information , Rust is a new language to me , I need a long time to learn it and understand the sccache's concept
