esp8266 - eagle.app.v6.common.ld is not created on build - build fails

[liebman]

Using the current git version of esp8266/Arduino has builds failing with the error:

/Users/chris.l/Dropbox/git/ESPNTPServer/hardware/esp8266com/esp8266/tools/xtensa-lx106-elf/bin/../lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld: cannot open linker script file ../ld/eagle.app.v6.common.ld: No such file or directory

and the platform.txt file has the rule:

Build the app.ld linker file

recipe.hooks.linking.prelink.1.pattern="{compiler.path}{compiler.c.cmd}" -CC -E -P {build.vtable_flags} "{runtime.platform.path}/tools/sdk/ld/eagle.app.v6.common.ld.h" -o "{runtime.platform.path}/tools/sdk/ld/eagle.app.v6.common.ld"

I believe this is to support being able to chose the vtable memory location (flash/iram/heap).

Sloeber does not seem to be processing this rule.

[jantje]

recipe.hooks.linking.prelink.1.pattern is currently not supported actually none of these "extra build commands" is currently supported.
I was thinking about adding pre and post build #927 but that was not a full solution.
I guess I'll have to take a deeper look now :-s

[jantje]

Could you try to replace in platform.txt
recipe.ar.pattern=XXXX
with
recipe.ar.pattern={recipe.hooks.linking.prelink.1.pattern};XXXX
After saving the file open the project properties select apply and ok and rebuild?

[liebman]

That works.

[jantje]

@liebman
Great :-) Thanks for the feedback
Can you share your full platform.txt as my first take was buggy and a patron has the same issue?

[liebman]

Its the stock one from the esp8266/Arduino git repo, master branch: https://github.com/esp8266/Arduino/blob/master/platform.txt - not one I really want to have to modify to be able to compile with the latest esp8266 core.

[jantje]

But you reported that the workaround worked for you so you must have a modified platform.txt you could share?

[jantje]

thanks

[jantje]

Seems the workaround only works in Linux because linus supports the ; to have multiple commands on one line.
I had expected make to handle this (as it did in other cases) but apparently it doesn't

[jantje]

The workaround should actually be done before the combiner and not the archiver
For windows one should use & and not ; to seperate the commands
So
recipe.c.combine.pattern=XXXX
on linux/mac should be replaced with
recipe.c.combine.pattern={recipe.hooks.linking.prelink.1.pattern};XXXX
on windows should be replaced with
recipe.c.combine.pattern={recipe.hooks.linking.prelink.1.pattern} & XXXX

[jantje]

@liebman
I fixed this to work with the platform.txt in the master of the github repository. However I didn't test on linux.
Ca you give this a try on linux with the nightly?

[liebman]

I'm on a Mac - I can test there. (mostly similar)

[jantje]

also good :-)

[liebman]

Works nicely on a Mac!

[jantje]

great thanks.

This issue has not been resolved . I am using the latest build of Eclipse and the current ESP8266 board installed yet I still get this error. I find it hard to believe this is still an issue after all this time.

Anyone out there have a clue what it takes to be able to build 8266 code in Arduino plugin for Eclipse? I can make ESP32, Arduino Uno & Mega firmware but ESP8266 has always failed when it tried to find this linker script.

Eclipse CDT	Arduino C++ Core	2.1.100.201902071800	org.eclipse.cdt.arduino.core
Eclipse CDT	Arduino C++ UI	2.1.200.201905061608	org.eclipse.cdt.arduino.ui

ESP8266 Platform 2.6.2

I am currently trying this on Windows but encounter the same problem with Linux.

Apparently hacking the platform.txt file does work but it should not have to be hacked.

[KareemMohamed1]

i faced the same problem . and then i have tried to hack the platform.txt with the solution provided by @jantje but i still have the same problem, it didnt work with me ,
Can anyone give a hand on thins, thanks in advance

[jantje]

Please open a new issue and attach your build output and other relevant info.

This issue is fixed an closed, you are probably experiencing another issue that looks alike.
