Can't build the latest release (1.9R7) with esp-idf v3.3

[elabree]

Hi,

I started recently to discover the possibliities of the EPS32.

But getting karadio working seems a bit difficult. I followed the steps in README.md and HardwareConfig.md. Result of make flash:

"C:/msys32/home/Egon/esp/Ka-Radio32/main/app_main.c:660:22: error: invalid initializer ip_addr_t ipdns0 = dns_getserver(0); ^ make[1]: *** [/home/Egon/esp/esp-idf/make/component_wrapper.mk:290: app_main.o] Fout 1 make: *** [C:/msys32/home/Egon/esp/esp-idf/make/project.mk:552: component-main-build] Fout 2 " I am not sure where to look. My mingw32 with esp-idf seems to be OK since I can built other projects correctly.

Any advise ? Kind Regards, Egon :-)

At C:\msys32\home\jp\esp\esp-idf\components\lwip\lwip\src\include\lwip\dns.h Line 109 ip_addr_t dns_getserver(u8_t numdns);

May be a compiler issue?

Try ip_addr_t ipdns0 ; ipdns0= dns_getserver(0);

In place of ip_addr_t ipdns0 = dns_getserver(0);

Hi, Thank you for the advise.

Egon@Q910 MINGW32 ~/esp/esp-idf $ git describe v3.3.2-26-g1ba3bf297 Egon@Q910 MINGW32 ~/esp/esp-idf $ git status -uno On branch release/v3.3 Your branch is up to date with 'origin/release/v3.3'.

The result after making the suggested change: "$ make flash Toolchain path: /opt/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc Toolchain version: crosstool-ng-1.22.0-80-g6c4433a5 Compiler version: 5.2.0 Python requirements from C:/msys32/home/Egon/esp/esp-idf/requirements.txt are satisfied.

So you are right: the latest esp-idf seems to have an issue. Thanks, Egon :-)

ip_addr_t *ipdns0 = dns_getserver(0); printf("\nDNS: %s \n",ip4addr_ntoa(( struct ip4_addr* ) ipdns0));

In $ git describe v3.3.2-107-g722043f73 At C:\msys32\home\jp\esp\esp-idf\components\lwip\lwip\src\include\lwip\dns.h Line 109 ip_addr_t dns_getserver(u8_t numdns); Changed to const ip_addr_t* dns_getserver(u8_t numdns);

So now you are right. The new code is ip_addr_t ipdns0 = dns_getserver(0); // ip_addr_t ipdns1 = dns_getserver(1); printf("\nDNS: %s \n",ip4addr_ntoa(( struct ip4_addr ) ipdns0));

Thanks
