From c6ca64081208e8b8c57c13619db366341f52cda3 Mon Sep 17 00:00:00 2001 From: Jesper Jensen Date: Sun, 6 Dec 2020 07:24:49 +0100 Subject: [PATCH] gcc 10 compatibility for Drop alt (#9485) * Split dmac_desc declaration and definition According to the official documentation[1] gcc 10 is more strict about correct extern usage. I've had to move the definition of dmac_desc and dmac_desc_wb from i2c_master.h to the corresponding .c file. This could be an issue if anyone includes the i2c_master.h file without liking with the object file. [1]: https://gcc.gnu.org/gcc-10/porting_to.html * Remove the keymap_config definition from keymaps The keymap_config def was conflicting with the one found in tmk_core/common/magic.c. Declaring it extern in magic.c breaks a bunch of keyboard that rely on that declaration (like the ergodox). Instead I've removed the one found in the keymap.c of the massdrop alt. The same change will have to be made to other keyboards. --- tmk_core/protocol/arm_atsam/i2c_master.c | 3 +++ tmk_core/protocol/arm_atsam/i2c_master.h | 4 ++-- 2 files changed, 5 insertions(+), 2 deletions(-) diff --git a/tmk_core/protocol/arm_atsam/i2c_master.c b/tmk_core/protocol/arm_atsam/i2c_master.c index d3319ab447d2..dda2f85b0019 100644 --- a/tmk_core/protocol/arm_atsam/i2c_master.c +++ b/tmk_core/protocol/arm_atsam/i2c_master.c @@ -28,6 +28,9 @@ along with this program.
