Thanks for the report, we will look into the cause of the issue, could you attach or email the "BuildFolder\.vmpreproc\SConsIncludePaths.txt" file for us to review?

Can you confirm the Gcc-E Deep Search Caching is working as expected for you, so performing a second build with Gcc-E is much quicker?
(Note: this is without changing to the Scons option in between the Gcc-E Builds)

Thanks for the update and clarification.

Is there a file in the "D:/temp/VMBuilds/version_1/esp32_d32/Release/.vmpreproc/SConsIncludePaths.txt"?

If that is present please attach it as it may help us to understand where the original error is coming from regarding Illegal Characters.

Thanks for the update and detail.

The paths are only around 100 chars so this should be a long way away from any long path limits.

Could you run the attached commands via the command line, and attach the file created D:/_WIP/arduino/libraries/AllLibraryFiles.txt ?

If you email it to info[at]visualmicro.com with a link to this post we will receive it.

Hi,

already send the dir cat file by email.

Before update to latest version for Gcc caching improvement
-first compile: 6min47sec = 407 sec
-second compile: 3min20 = 200 sec = 51% faster

Tried the new version Gcc:
- 1st compile: 7min25sec = 445 sec
-2nd compile: 3min18sec = 198 sec = 56% faster, but with first compile slower

So maybe a slight improvement with the new version of visual studio, but not obvious.

Please let me know once you reviewed the dircat, could not spot anything obvious.

Thanks in advance

Hi,

Would really appreciate a solution for SCons as with Gcc compiling times make programming very painful.

Cheers

Hi,

thanks for following up. New log attached.

Hi,

I have tried with the latest version as advised in your email (2024.0718.0).

Please see log attached. As I couldn't see much in the log, I have run some test and there is a very weird behavior: If the word "fatal" is used in the prog, even commented, the compile file with illegal characters in path.

The program compiles fine with the following lines (extract, over 1420 lines):

void update_error(int err) {
    Serial.print(F("CALLBACK:  HTTP update fatalx error code:"));
    Serial.println(err);
}
 

BUT NOT with

void update_error(int err) {
    Serial.print(F("CALLBACK:  HTTP update fatal error code:"));
    Serial.println(err);
}
 

There is also another stange behavior: the compiler could not deal with function definitions positioned after their use at first go, then would work fine if I moved just one function definition for one compile (repositioning it after)???

Otherwise, compile time with SCons is down to 1min48.

Please advise on the issues highlighted.

Thanks in advance
BR

PS: I have tried with different encodings and it does not make a difference, if "fatal" is in the code, even commented, compile fails
