Errors on compiling after a fresh git clone #2309

Closed teicors closed 3 years ago

teicors commented 3 years ago

Hi, I cloned today the git repository and issuing a make, I got this error:

Try first make -C $SMING_HOME dist-clean after that clean your application cd <path/to/app>; make clean and finally try to rebuild it.

mikee47 commented 3 years ago

@teicors Assuming you've done as as slaff suggests, if the problem persists could you amend Sming/Components/IFS/src/HostUtil.cpp as follows and see if that fixes your problem:


#include <string.h>
#undef strerror_r ///< Add this line
extern "C" char* strerror_r(int, char*, size_t);
kmihaylov commented 3 years ago

@teicors would you please recheck if you set ESP_HOME and EQT_ROOT environment variables?

env | grep -E "EQT|ESP"

You should get result like

EQT_ROOT=/opt/esp-quick-toolchain
ESP_HOME=/opt/esp-quick-toolchain

@slaff @mikee47 I believe it would be helpful if the make script checks somehow for proper compiler, since just a few minutes ago I had the same problem as @teicors and it happened that my env variables were missing. Curious how it successfully compiles most of the stuff before HostUtil.cpp.

teicors commented 3 years ago

@kmihaylov here's my result:

(base) angelo@angelo-thinkpad-x1-carbon-4th:~/Software/esp8266/project/rsyslog_client$ env | grep -E "EQT|ESP"
ESP_HOME=/opt/esp-quick-toolchain
(base) angelo@angelo-thinkpad-x1-carbon-4th:~/Software/esp8266/project/rsyslog_client$

I'm missing the EQT_ROOT=/opt/esp-quick-toolchain

but

I added the line as @mikee47 suggested, but the only change is the line number changed from 24 to 25 :)

I forgot: I did the @slaff suggestion as first step !

mikee47 commented 3 years ago

@teicors This error:

/opt/esp-quick-toolchain/xtensa-lx106-elf/xtensa-lx106-elf/include/string.h:106:5: note: previous declaration 'int strerror_r(int, char*, size_t)'
  106 | int _EXFUN(strerror_r,(int, char *, size_t))

refers to a line which doesn't exist in ESP quick toolchain version gnu20, which is the version used by the default installer (and CI tests). May I suggest installing that version instead? It's the version used for all the CI testing.

Here's the linux link:

https://github.com/earlephilhower/esp-quick-toolchain/releases/download/3.0.0-newlib4.0.0-gnu20/x86_64-linux-gnu.xtensa-lx106-elf-e6a192b.201211.tar.gz

@mikee47 the new version solves my issue.

But I'm facing another issue: I cannot compile an old project because

But there were nothing inside the file component.mk. The value was inside the file config.mk:

May be exists a make's parameter to clean the old build/configuration ? Don't say "config-clean" or "dist-clean" please :) No luck with "make components-clean submodules-clean part-clean"

But as usual, THANKS !

mikee47 commented 3 years ago

LOL. I'm going to say it. config-clean! All it does is remove out/Esp8266/build/config.mk (or whatever arch/build is currently set). If you don't want to do that, just edit the config.mk file and remove the lines manually - you'll need to remove both references to DISABLE_SPIFFS.

If that doesn't fix the problem then check DISABLE_SPIFFS isn't set in the environment? And run grep on the Sming repo too...

teicors commented 3 years ago

mmhh make config-clean make SMING_ARCH=Esp8266 SPI_MODE=dio SPI_SIZE=4M COM_SPEED_ESPTOOL=1000000 SPIFF_SIZE=511024 SDK_BASE='$(SMING_HOME)' COM_PORT=/dev/ttyUSB3 Paris vaut une messe ! No more headache ! LOL
