Error on compile

[crosofg]

Hi I am receiving error upon compiling. gcc -O2 -Wall -c esptool2.c -o esptool2.o In file included from esptool2.c:26: esptool2.h:33:20: stdint.h: No such file or directory In file included from esptool2_elf.h:27, from esptool2.c:27: elf.h:25: error: parse error before "Elf32_Addr" elf.h:25: warning: type defaults to int' in declaration ofElf32_Addr' elf.h:25: warning: data definition has no type or storage class elf.h:26: error: parse error before "Elf32_Off" elf.h:26: warning: type defaults to int' in declaration ofElf32_Off' elf.h:26: warning: data definition has no type or storage class elf.h:27: error: parse error before "Elf32_Half"

This was building sometime back.

Problem is that you're missing stdint.h, what platform and compiler are you using? The only change that has been made to esptool2 recently was the addition of the -Wall option, so perhaps it was happily ignoring this defaulting before. Easiest fix might be to remove that option.

I am using Windows 10 and Mingw. I removed -Wall , still the same error.

That's odd, as I say the only recent change (since June) was the addition of that one CFLAG. Has anything changed on your system recently (aside from moving to Windows 10, can't imagine that's the issue)? New version of mingw?

At the top of esptool.h you'll find this:

ifdef WIN32

typedef signed int8 int8_t; typedef signed __int16 int16_t; typedef signed int32 int32_t; typedef unsigned int8 uint8_t; typedef unsigned __int16 uint16_t; typedef unsigned int32 uint32_t;

else

include

endif

Change the #ifdef WIN32 to #if defined WIN32 || defined __MINGW32__ or failing that just make the typedefs unconditional and remove the include of stdint.h.

fixed the markdown, it was messing up the code to add

Did this work?

[crosofg]

No it didnt work in windows env. I installed the virtual box and setup a linux env. The esptool2 compiled and generated .o files. Then I changed all the paths in the subdirectory's makefile. (From c:/espressif to /opt/esp-open-sdk) and ran the root make to compile everything.

I must admit I've now moved my development to Linux. Getting everything to work on windows in the first place took more effort, but I thought it was probably still easier than setting up a Linux dev system in virtual box. When I started to work with Sming it just wasn't playing ball so I decided the investment in time was probably better spent on setting up a Linux image. It didn't actually take much effort at all, I should have done it sooner! Your problem is still odd though, because nothing changed in the code that would explain why it used to work then stopped. I'll close this issue and if anyone else hits it and wants to persist with windows I can look into it further then.
