Hi, I'm trying to build the BLE sample following the [Set up a bare bones NimBLE application](https://mynewt.apache.org/latest/tutorials/ble/ble_bare_bones.html). I'm working on Ubuntu 20.04 with WSL2. There is one step in the doc to add following configuration in syscfg.yml: ``` syscfg.vals: BLE_HCI_TRANSPORT: builtin ``` When I ran `newt build ble_tgt`, the following error appeared: ``` Building target targets/ble_tgt Error: Override of defunct settings detected: BLE_HCI_TRANSPORT: see doc/transport.md Setting history (newest -> oldest): BLE_HCI_TRANSPORT: [apps/ble_app:builtin, @apache-mynewt-nimble/nimble/transport:] ``` It seems that the `BLE_HCI_TRANSPORT` has been removed(the tutorial is outdated). So I temporarily removed the config in syscfg.yml, but then I got another error while building: ``` Error: repos/apache-mynewt-core/encoding/tinycbor/src/cborpretty.c: In function 'value_to_pretty': repos/apache-mynewt-core/encoding/tinycbor/src/cborpretty.c:334:33: error: expected ')' before 'PRIu64' 334 | if (fprintf(out, "%" PRIu64, val) < 0) | ^~~~~~~ | ) repos/apache-mynewt-core/encoding/tinycbor/src/cborpretty.c:334:31: error: spurious trailing '%' in format [-Werror=format=] 334 | if (fprintf(out, "%" PRIu64, val) < 0) | ^ repos/apache-mynewt-core/encoding/tinycbor/src/cborpretty.c:343:38: error: expected ')' before 'PRIu64' 343 | if (fprintf(out, "-%" PRIu64, val) < 0) | ^~~~~~~ | ) repos/apache-mynewt-core/encoding/tinycbor/src/cborpretty.c:343:36: error: spurious trailing '%' in format [-Werror=format=] 343 | if (fprintf(out, "-%" PRIu64, val) < 0) | ^ repos/apache-mynewt-core/encoding/tinycbor/src/cborpretty.c:390:29: error: expected ')' before 'PRIu64' 390 | if (fprintf(out, "%" PRIu64 "(", tag) < 0) | ^~~~~~~ | ) repos/apache-mynewt-core/encoding/tinycbor/src/cborpretty.c:390:27: error: spurious trailing '%' in format [-Werror=format=] 390 | if (fprintf(out, "%" PRIu64 "(", tag) < 0) | ^ cc1: all warnings being treated as errors ``` [Solutions ](https://stackoverflow.com/questions/8132399/how-to-printf-uint64-t-fails-with-spurious-trailing-in-format) I can find all suggest that this is a C99 standard problem. I have added below code to `repos/apache-mynewt-core/encoding/tinycbor/src/cborpretty.c` and `repos/apache-mynewt-core/encoding/tinycbor/src/cbortojson.c`: ``` #define __STDC_FORMAT_MACROS 1 ... #include <inttypes.h> ``` But it doesn't solve the problem. My compiler version is `arm-none-eabi-g++ (15:9-2019-q4-0ubuntu1) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]`. What is the suggesting version of gcc to build MynewtOS? I find no `__STDC_FORMAT_MACROS` in the entire Mynewt repo. Does it mean thiserror has never occurred before? -- This is an automated message from the Apache Git Service.
