From 904b1b3f99201f4bead195e2b777a71cb25736d8 Mon Sep 17 00:00:00 2001 From: Erin Call Date: Mon, 22 Jan 2018 14:11:46 -0800 Subject: [PATCH] Use perl directly instead of grep -P BSD grep (the one on OSX) lacks a -P flag. The grep -P command thus fails and prints a usage message to the terminal. This fixes that. --- tmk_core/rules.mk | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tmk_core/rules.mk b/tmk_core/rules.mk index 7a282cacc..a1df7fc28 100644 --- a/tmk_core/rules.mk +++ b/tmk_core/rules.mk @@ -371,7 +371,7 @@ show_path: @echo OBJ=$(OBJ) check-size: - $(eval MAX_SIZE=$(shell n=`avr-gcc -E -mmcu=$(MCU) $(CFLAGS) $(OPT_DEFS) tmk_core/common/avr/bootloader_size.c 2> /dev/null | grep -oP "(?<=AVR_SIZE: ).+"`; echo $$(($$n)) || echo 0)) + $(eval MAX_SIZE=$(shell n=`avr-gcc -E -mmcu=$(MCU) $(CFLAGS) $(OPT_DEFS) tmk_core/common/avr/bootloader_size.c 2> /dev/null | perl -ne 'print "$&\n" if /(?<=AVR_SIZE: ).+/'`; echo $$(($$n)) || echo 0)) $(eval CURRENT_SIZE=$(shell if [ -f $(BUILD_DIR)/$(TARGET).hex ]; then $(SIZE) --target=$(FORMAT) $(BUILD_DIR)/$(TARGET).hex | $(AWK) 'NR==2 {print $$4}'; else printf 0; fi)) if [ $(MAX_SIZE) -gt 0 ] && [ $(CURRENT_SIZE) -gt 0 ]; then \ $(SILENT) || printf "$(MSG_CHECK_FILESIZE)" | $(AWK_CMD); \
