ble.h compiling error with GCC C++

[armin]

Hi

We develop an application on nRF51822 the with GCC C++ and try to include the file ble.h in a .cpp file. As soon when I include the file in the .cpp file I get compiling errors that SVCALL isn't defined.

I included it with the extern "C" definition, did not help either.

"#"ifdef __cplusplus extern "C" { "#"endif

"#"include "ble.h" "#"ifdef __cplusplus } "#"endif

The Compiler errors:

arm-eabi\com.sysprogs.arm.nordic.nrf5x/nRF51/components/softdevice/S110/headers/ble_gap.h: In function 'uint32_t sd_ble_gap_auth_key_reply(uint16_t, uint8_t, const uint8_t*)':

warning : asm operand 0 probably doesn't match constraints

arm-eabi\com.sysprogs.arm.nordic.nrf5x\nRF51\components\softdevice\S110\headers\ble_gap.h(1206,1): note: in expansion of macro 'SVCALL' 1> SVCALL(SD_BLE_GAP_AUTH_KEY_REPLY, uint32_t, sd_ble_gap_auth_key_reply(uint16_t conn_handle, uint8_t key_type, uint8_t const *p_key));

Compiler CFlags: "-ffunction-sections -O0" CXXFLAGS: "-ffunction-sections -fno-exceptions -fno-rtti -O0 -std=c++11"

Is there any other flag on the compiler to set? I mean, we compiled other nRF libraries without any problems, which call SVCALL as well.

Thanks, Armin

Yes this bug is very annoying - if you'd used the search at the top of the page you would have found your answer very quickly, it's been outstanding for a while.

add the cast, it'll work. I reported this again a week or so ago, hopefully it'll make it into the SDK at some point although I've gotten to the point now I just fix every SDK which comes out.

These header files are owned by softdevice team and we had hard time convincing them to prioritize this task. This has been fixed and released in s132_nrf52_2.0.0-8.alpha. On S130, it is fixed but will be released in next release.
