Build issue on the mips platform about snoopy

[bostjan]

Much appreciated, @condemil. I'll give it a go in the coming days/weeks/months.

@condemil, can you think of a way where I can test out this build variation myself? I.e. is there a hosting service where I can rent a mips system for a few hours?

I am using OpenWRT SDK to cross-compile the sources. You can follow these steps to do the same:

sudo apt install gawk
mkdir -p $HOME/openwrt
cd $HOME/openwrt
git clone https://github.com/a2o/snoopy
wget https://downloads.openwrt.org/releases/22.03.2/targets/ath79/nand/openwrt-sdk-22.03.2-ath79-nand_gcc-11.2.0_musl.Linux-x86_64.tar.xz -O openwrt.tar.xz
tar xf openwrt.tar.xz
export SDK=$HOME/openwrt/openwrt-sdk-22.03.2-ath79-nand_gcc-11.2.0_musl.Linux-x86_64
export PATH=$SDK/staging_dir/host/bin:$PATH
mkdir -p mypackages/snoopy
ln -s $HOME/openwrt/snoopy/.git $HOME/openwrt/mypackages/snoopy/git-src

create file mypackages/snoopy/Makefile with the following contents:

include $(TOPDIR)/rules.mk

PKG_NAME:=snoopy
PKG_VERSION:=2.5.1
PKG_RELEASE:=1

PKG_BUILD_DIR:=$(BUILD_DIR)/snoopy-$(PKG_VERSION)

PKG_SOURCE_PROTO:=git
PKG_SOURCE_URL:=https://github.com/a2o/snoopy.git
PKG_SOURCE_VERSION:=snoopy-$(PKG_VERSION)

PKG_FIXUP:=autoreconf

include $(INCLUDE_DIR)/package.mk

define Package/snoopy
	SECTION:=base
	CATEGORY:=Utilities
	TITLE:=Snoopy Command Logger
	URL:=https://github.com/a2o/snoopy
endef

define Package/snoopy/description
	Snoopy Command Logger is a small library that logs all program
	executions on your system.
endef

define Build/Configure
	$(call Build/Configure/Default,--with-linux-headers=$(LINUX_DIR))
endef

define Package/snoopy/install
	$(INSTALL_DIR) $(1)/usr/local/lib
	$(INSTALL_DATA) $(PKG_BUILD_DIR)/libsnoopy.so $(1)/usr/local/lib/libsnoopy.so
endef

$(eval $(call BuildPackage,snoopy))

call these commands:

cd $SDK
echo "src-link mypackages $HOME/openwrt/mypackages" > $SDK/feeds.conf
./scripts/feeds update mypackages
./scripts/feeds install -a -p mypackages
make package/snoopy/compile -j1 V=s

In menuconfig make sure these are enabled:

Advanced configuration options (for developers) -> Enable package source tree override (NEW)
Utilities -> snoopy

Once you do changes in the code under $HOME/openwrt/snoopy git repo you need to commit those changes as OpenWRT build system takes sources from git HEAD for package source tree override mode.
