OpenWrt 18.06 cannot compile my project with depends libmysqlclient

Can anyone help me?
I can't compile my project for Mikrotik device (but in LEDE 17.01 is no problem).
Errors while compiling:

My Makefile:

include $(TOPDIR)/
include $(INCLUDE_DIR)/
include $(INCLUDE_DIR)/


define Package/marcontrol
	TITLE:=MaR Technology s.r.o. Control system
	MAINTAINER:=Richard Neuwirth <>
	DEPENDS:=+libmodbus +libmysqlclient +libpthread +libconfig

define Build/Prepare
	mkdir -p $(PKG_BUILD_DIR)

define Build/Compile
	$(TARGET_CC) $(TARGET_CFLAGS) $(TARGET_LDFLAGS) -luClibc++ -o $(PKG_BUILD_DIR)/marcon marcon.cpp -lpthread `pkg-config --cflags --libs libmodbus` `pkg-config --cflags --libs libconfig` `mysql_config --cflags --libs`

define Package/marcontrol/install
	$(INSTALL_DIR) $(1)/bin
	$(INSTALL_BIN) $(PKG_BUILD_DIR)/marcon $(1)/bin/

$(eval $(call BuildPackage,marcontrol))

What I doing wrong?

Not a standard library -- needs to be a dependency

Side note: The preformatted-text button </> makes terminal output a lot easier to read.

Is there some "standard" library alternative?

“Standard” meaning not always available without requesting it. C++ libraries aren’t installed by default, due to space constraints.

This works for me when needing to run a C/C++ binary on OpenWrt.

You probably need to add +uclibcxx to the DEPENDS:= line of your makefile. It is possible that one of the libraries you depend on implicitly pulled in libuClibc++ in the past but does not do so anymore.

Assuming that libstdc++ is all that is required by your program, it should be enough to simply remove the explicit -luClibc++ linkage from your Build/Compile line.


Adding +uclibcxx into DEPENDS solve this problem, thank you for your help guys...
