Hi, my name is Cristian, I'm writing from Chile I'm trying to install the driver for my RTL8821CE card. I'm following the instructions from the repo https://github.com/lwfinger/rtw88 (I took the email from there) but when I try to run the "make" command, I get the following error: /home/cristian/Downloads/realtek_drivers/rtw88/main.c: In function ‘rtw_core_init’: /home/cristian/Downloads/realtek_drivers/rtw88/main.c:1623:2: error: implicit declaration of function ‘tasklet_setup’ [-Werror=implicit-function-declaration] 1623 | tasklet_setup(&rtwdev->tx_tasklet, rtw_tx_tasklet); this is the output from "sudo lshw -C network" and the full log of the error. =========== cristian@cristian-HP-240-G7-Notebook-PC:~/Downloads/realtek_drivers/rtw88$ sudo lshw -C network *-network description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 logical name: enp1s0 version: 15 serial: 84:2a:fd:5a:7f:6e capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 firmware=rtl8168h-2_0.0.2 02/26/15 latency=0 link=no multicast=yes port=MII resources: irq:19 ioport:4000(size=256) memory:80504000-80504fff memory:80500000-80503fff *-network UNCLAIMED description: Network controller product: RTL8821CE 802.11ac PCIe Wireless Network Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: ioport:3000(size=256) memory:80400000-8040ffff cristian@cristian-HP-240-G7-Notebook-PC:~/Downloads/realtek_drivers/rtw88$ cristian@cristian-HP-240-G7-Notebook-PC:~/Downloads/realtek_drivers/rtw88$ ls bf.c debug.o mac80211.o phy.c rtw8723de.h rtw8821c_table.c rtw8822ce.c sec.c bf.h dkms.conf mac.c phy.h rtw8723d_fw.bin rtw8821c_table.h rtw8822ce.h sec.h bitfield.h efuse.c mac.h ps.c rtw8723d.h rtw8822b.c rtw8822c_fw.bin sign-file certificate.p12 efuse.h main.c ps.h rtw8723d_table.c rtw8822be.c rtw8822c.h tx.c certificate.pem fw.c main.h README.md rtw8723d_table.h rtw8822be.h rtw8822c_table.c tx.h coex.c fw.h main.o regd.c rtw8821c.c rtw8822b_fw.bin rtw8822c_table.h util.c coex.h hci.h Makefile regd.h rtw8821ce.c rtw8822b.h rtw8822c_wow_fw.bin util.h compiler.h kernel_key.pem openssl.conf reg.h rtw8821ce.h rtw8822b_table.c rx.c util.o debug.c key.pem pci.c rtw8723d.c rtw8821c_fw.bin rtw8822b_table.h rx.h wow.c debug.h mac80211.c pci.h rtw8723de.c rtw8821c.h rtw8822c.c sch_generic.h wow.h cristian@cristian-HP-240-G7-Notebook-PC:~/Downloads/realtek_drivers/rtw88$ make make -C /lib/modules/5.4.0-42-generic/build M=/home/cristian/Downloads/realtek_drivers/rtw88 modules make1: Entering directory '/usr/src/linux-headers-5.4.0-42-generic' CC M /home/cristian/Downloads/realtek_drivers/rtw88/main.o /home/cristian/Downloads/realtek_drivers/rtw88/main.c: In function rtw_core_init: /home/cristian/Downloads/realtek_drivers/rtw88/main.c:1623:2: error: implicit declaration of function tasklet_setup -Werror=implicit-function-declaration 1623 tasklet_setup(&rtwdev->tx_tasklet, rtw_tx_tasklet); cc1: some warnings being treated as errors make2: *** scripts/Makefile.build:275: /home/cristian/Downloads/realtek_drivers/rtw88/main.o Error 1 make1: *** Makefile:1731: /home/cristian/Downloads/realtek_drivers/rtw88 Error 2 make1: Leaving directory '/usr/src/linux-headers-5.4.0-42-generic' make: *** Makefile:79: all Error 2 cristian@cristian-HP-240-G7-Notebook-PC:~/Downloads/realtek_drivers/rtw88$ sudo make install sudo password for cristian: make -C /lib/modules/5.4.0-42-generic/build M=/home/cristian/Downloads/realtek_drivers/rtw88 modules make1: Entering directory '/usr/src/linux-headers-5.4.0-42-generic' CC M /home/cristian/Downloads/realtek_drivers/rtw88/main.o /home/cristian/Downloads/realtek_drivers/rtw88/main.c: In function rtw_core_init: /home/cristian/Downloads/realtek_drivers/rtw88/main.c:1623:2: error: implicit declaration of function tasklet_setup -Werror=implicit-function-declaration 1623 | tasklet_setup(&rtwdev->tx_tasklet, rtw_tx_tasklet); cc1: some warnings being treated as errors make2: *** scripts/Makefile.build:275: /home/cristian/Downloads/realtek_drivers/rtw88/main.o Error 1 make1: *** Makefile:1731: /home/cristian/Downloads/realtek_drivers/rtw88 Error 2 make1: Leaving directory '/usr/src/linux-headers-5.4.0-42-generic' make: *** Makefile:79: all Error 2 cristian@cristian-HP-240-G7-Notebook-PC:~/Downloads/realtek_drivers/rtw88$ =========== Thanks, and greetings from Chile! -- Cristian Llanos Montenegro +56 9 9618 8576
